00:00:38,280 --> 00:00:40,879
hello and welcome to our BBC microbic

4
00:00:40,879 --> 00:00:44,440
Global codal my name is Giles and my

5
00:00:44,440 --> 00:00:46,239
name is blaed and we are part of the

6
00:00:46,239 --> 00:00:48,399
Education team here at the microbit

7
00:00:48,399 --> 00:00:51,440
Educational Foundation now does anyone

8
00:00:51,440 --> 00:00:55,079
know the theme of today's Cod along here

9
00:00:55,079 --> 00:00:57,920
are a few

10
00:00:58,120 --> 00:01:01,719
Clues there a butterfly

11
00:01:01,719 --> 00:01:06,400
F uh oh okay that looks like some

12
00:01:06,400 --> 00:01:10,400
flowers well that's definitely a

13
00:01:11,320 --> 00:01:15,159
tree oh my goodness a very large Robin a

14
00:01:15,159 --> 00:01:17,200
very large

15
00:01:17,200 --> 00:01:20,479
bird so well done anyone watching if you

16
00:01:20,479 --> 00:01:23,079
have shouted out the theme is

17
00:01:23,079 --> 00:01:25,600
biodiversity happy International Day for

18
00:01:25,600 --> 00:01:29,280
biological diversity um or International

19
00:01:29,280 --> 00:01:31,040
Day for bio biodiversity as it can be

20
00:01:31,040 --> 00:01:34,720
shortened to the United Nations theme uh

21
00:01:34,720 --> 00:01:37,439
this year is all about building back

22
00:01:37,439 --> 00:01:40,240
biodiversity because we all depend on a

23
00:01:40,240 --> 00:01:46,040
wide variety of plants and animals and

24
00:01:46,040 --> 00:01:48,880
microorganisms to keep us all healthy

25
00:01:48,880 --> 00:01:52,360
and thriving so in today's codal along

26
00:01:52,360 --> 00:01:54,600
you are going to be doing your bit as

27
00:01:54,600 --> 00:01:56,039
well because you are going to be

28
00:01:56,039 --> 00:01:58,960
building back bio biodiversity too by

29
00:01:58,960 --> 00:02:01,680
creating a bi biodiversity counter that

30
00:02:01,680 --> 00:02:03,920
can be used in your school playground or

31
00:02:03,920 --> 00:02:06,320
any other outdoor area you have near

32
00:02:06,320 --> 00:02:09,520
your school and as today is UN day for

33
00:02:09,520 --> 00:02:12,599
biodiversity the plan is to create uh

34
00:02:12,599 --> 00:02:15,720
the project in the make code editor but

35
00:02:15,720 --> 00:02:17,640
then to transfer the code onto the

36
00:02:17,640 --> 00:02:20,239
microbit and use them outside to count

37
00:02:20,239 --> 00:02:22,000
the number of species of animals and

38
00:02:22,000 --> 00:02:24,640
species of plants that you can spot you

39
00:02:24,640 --> 00:02:26,560
don't need a microbit to take part in

40
00:02:26,560 --> 00:02:28,519
this session as we will be making good

41
00:02:28,519 --> 00:02:30,480
use of the simulator on make code

42
00:02:30,480 --> 00:02:33,040
website but if you do have microbits

43
00:02:33,040 --> 00:02:34,599
then make sure you have them out ready

44
00:02:34,599 --> 00:02:36,720
to put the code on at the end of the

45
00:02:36,720 --> 00:02:39,120
session and in today's session we're

46
00:02:39,120 --> 00:02:41,560
going to be coding along together make

47
00:02:41,560 --> 00:02:44,159
sure that you pause the video whenever

48
00:02:44,159 --> 00:02:46,480
you need to and you can replay parts

49
00:02:46,480 --> 00:02:49,640
that you need to hear over again I'm

50
00:02:49,640 --> 00:02:51,200
really excited that we're coding the

51
00:02:51,200 --> 00:02:53,440
biodiversity cter together so students

52
00:02:53,440 --> 00:02:55,200
all over the world can see what their

53
00:02:55,200 --> 00:02:58,519
local biodiversity is like if you have a

54
00:02:58,519 --> 00:03:01,080
school Twitter or X account then make

55
00:03:01,080 --> 00:03:05,040
sure you share how you get on you can

56
00:03:05,040 --> 00:03:10,239
tag us we are at microbit uncore edu

57
00:03:10,239 --> 00:03:14,319
that's microbit uncore edu on Twitter or

58
00:03:14,319 --> 00:03:17,519
X that's a really good idea J it will be

59
00:03:17,519 --> 00:03:19,720
lovely to see how different classes and

60
00:03:19,720 --> 00:03:22,599
schools get on in their environments so

61
00:03:22,599 --> 00:03:25,280
I think we're ready to get started Giles

62
00:03:25,280 --> 00:03:26,640
can you think of anything else we need

63
00:03:26,640 --> 00:03:29,360
to mention before we start coding I

64
00:03:29,360 --> 00:03:31,799
think as we're making a species counter

65
00:03:31,799 --> 00:03:33,319
I think it would be really good just to

66
00:03:33,319 --> 00:03:35,319
make sure that everyone knows exactly

67
00:03:35,319 --> 00:03:39,200
what a species is great call Giles okay

68
00:03:39,200 --> 00:03:42,159
so a species is a set of animals or

69
00:03:42,159 --> 00:03:45,040
plants who have similar characteristics

70
00:03:45,040 --> 00:03:46,959
to each other so they all look similar

71
00:03:46,959 --> 00:03:48,319
to each other and they have similar

72
00:03:48,319 --> 00:03:50,680
characteristics so for

73
00:03:50,680 --> 00:03:53,400
example let's look at these pictures

74
00:03:53,400 --> 00:03:56,280
here so let me just remove this so that

75
00:03:56,280 --> 00:04:00,239
you can see it better there we go so so

76
00:04:00,239 --> 00:04:02,920
um in the in the slide here we've got

77
00:04:02,920 --> 00:04:05,599
lots of different animals but how many

78
00:04:05,599 --> 00:04:08,319
species have we got Giles oh that's a

79
00:04:08,319 --> 00:04:09,920
really interesting question it's quite

80
00:04:09,920 --> 00:04:11,720
tricky actually um I'm going to start

81
00:04:11,720 --> 00:04:13,879
with the ones that all look the same so

82
00:04:13,879 --> 00:04:17,199
I can see some snails there um some in

83
00:04:17,199 --> 00:04:19,639
their shells some out of their shells so

84
00:04:19,639 --> 00:04:21,759
I think the three pictures of snails

85
00:04:21,759 --> 00:04:23,479
that's one

86
00:04:23,479 --> 00:04:27,199
species um I can see Robin again a bird

87
00:04:27,199 --> 00:04:28,800
and I don't see any other birds on there

88
00:04:28,800 --> 00:04:31,160
so I think that's probably another

89
00:04:31,160 --> 00:04:35,840
species um we've got oh two butterflies

90
00:04:35,840 --> 00:04:38,960
so I think two butterflies uh probably

91
00:04:38,960 --> 00:04:43,199
one more species and then I can see a

92
00:04:43,199 --> 00:04:47,000
fly and I can see a worms so I think

93
00:04:47,000 --> 00:04:49,759
have we got five species there blonded

94
00:04:49,759 --> 00:04:53,360
well done yes I think that is spot on

95
00:04:53,360 --> 00:04:54,840
and that means that everyone is very

96
00:04:54,840 --> 00:04:56,759
clear and everyone can be super accurate

97
00:04:56,759 --> 00:04:58,320
when they go out and they start logging

98
00:04:58,320 --> 00:05:01,560
their species later thanks chares so

99
00:05:01,560 --> 00:05:05,720
let's get coding um so the what we're

100
00:05:05,720 --> 00:05:07,160
going to do is we're going to bring you

101
00:05:07,160 --> 00:05:09,720
to the makecode editor

102
00:05:09,720 --> 00:05:13,000
website so um you'll find that you can

103
00:05:13,000 --> 00:05:15,320
see it on the banner now at make code.

104
00:05:15,320 --> 00:05:18,080
microbit

105
00:05:29,720 --> 00:05:31,520
you can get started with right away

106
00:05:31,520 --> 00:05:34,520
without needing any logins or passwords

107
00:05:34,520 --> 00:05:36,280
and so on so there is a sign-in button

108
00:05:36,280 --> 00:05:37,800
on the top right so schools with

109
00:05:37,800 --> 00:05:39,960
Microsoft or Google logins can use that

110
00:05:39,960 --> 00:05:41,680
but we don't need to we can jump

111
00:05:41,680 --> 00:05:44,160
straight in um now I've got some

112
00:05:44,160 --> 00:05:46,199
projects showing here because I've used

113
00:05:46,199 --> 00:05:48,039
it before if it's your first time you

114
00:05:48,039 --> 00:05:50,440
might not have that but you will have

115
00:05:50,440 --> 00:05:52,479
new project the new project button and

116
00:05:52,479 --> 00:05:53,800
that's what we're going to jump straight

117
00:05:53,800 --> 00:05:56,759
into also in the settings on make code

118
00:05:56,759 --> 00:05:58,560
in the top right there's a little Cog

119
00:05:58,560 --> 00:06:00,720
here next to the sign-in button that's

120
00:06:00,720 --> 00:06:02,560
where you'll find different languages if

121
00:06:02,560 --> 00:06:04,680
you want to change the language to to

122
00:06:04,680 --> 00:06:09,400
your local language so click on new

123
00:06:09,400 --> 00:06:11,680
project and the first thing it does is

124
00:06:11,680 --> 00:06:14,120
asks me to give it a name so if you're

125
00:06:14,120 --> 00:06:16,680
doing the same project as the CL it's a

126
00:06:16,680 --> 00:06:19,120
really good idea to make sure that your

127
00:06:19,120 --> 00:06:21,400
name or your student name is is is

128
00:06:21,400 --> 00:06:24,360
included in the project name and today

129
00:06:24,360 --> 00:06:28,000
we're making a biodiversity counter so

130
00:06:28,000 --> 00:06:29,840
I'm going to name my project blana

131
00:06:29,840 --> 00:06:33,800
biodiversity counter and click on

132
00:06:33,800 --> 00:06:36,520
create okay so this has opened up the

133
00:06:36,520 --> 00:06:39,800
make code editor so we can see that

134
00:06:39,800 --> 00:06:41,759
there's some blocks of code already in

135
00:06:41,759 --> 00:06:43,400
the workspace here on the right now I'm

136
00:06:43,400 --> 00:06:45,120
going to make that a little bit bigger

137
00:06:45,120 --> 00:06:47,120
by using this plus sign in the bottom

138
00:06:47,120 --> 00:06:49,240
right hand side going to zoom in on my

139
00:06:49,240 --> 00:06:51,800
blocks of code a little bit do you think

140
00:06:51,800 --> 00:06:53,720
that's large enough Giles I think so I

141
00:06:53,720 --> 00:06:55,000
can see that really clearly thank you

142
00:06:55,000 --> 00:06:58,080
blet okay brilliant so um this is the

143
00:06:58,080 --> 00:06:59,599
workspace this is where you can draw

144
00:06:59,599 --> 00:07:01,639
drag blocks of codee around and you drag

145
00:07:01,639 --> 00:07:03,680
them in from the toolbox over here and

146
00:07:03,680 --> 00:07:06,199
you build your code in this space now we

147
00:07:06,199 --> 00:07:08,160
won't need the forever block for our

148
00:07:08,160 --> 00:07:09,560
project today so I'm actually going to

149
00:07:09,560 --> 00:07:11,160
show you how to delete the blocks as

150
00:07:11,160 --> 00:07:14,919
well by dragging them onto the uh the

151
00:07:14,919 --> 00:07:17,080
the menu here or the toolbox and then

152
00:07:17,080 --> 00:07:19,080
just letting go and it will delete a

153
00:07:19,080 --> 00:07:22,400
block um when you have a look inside

154
00:07:22,400 --> 00:07:24,120
this menu you can see that there's lots

155
00:07:24,120 --> 00:07:27,080
of pre-prepared blocks of code ready to

156
00:07:27,080 --> 00:07:29,720
go you don't need to have to know what

157
00:07:29,720 --> 00:07:32,160
to type like you would in a text based

158
00:07:32,160 --> 00:07:34,800
um editor you can just take the blocks

159
00:07:34,800 --> 00:07:36,639
and you can drag and drop them onto the

160
00:07:36,639 --> 00:07:38,520
workspace as you need

161
00:07:38,520 --> 00:07:41,360
them um on the left hand side here we've

162
00:07:41,360 --> 00:07:44,319
also got the simulator so we'll be using

163
00:07:44,319 --> 00:07:46,240
this today to check that everything is

164
00:07:46,240 --> 00:07:48,840
working before we put our code on our

165
00:07:48,840 --> 00:07:51,919
microbit and take them outside to do our

166
00:07:51,919 --> 00:07:55,720
biodiversity logging um we'll also be

167
00:07:55,720 --> 00:07:58,360
using the download button we just take

168
00:07:58,360 --> 00:08:00,039
off the banner for a second perfect

169
00:08:00,039 --> 00:08:02,360
thank you Giles so the download button

170
00:08:02,360 --> 00:08:04,120
here bottom left that will be used at

171
00:08:04,120 --> 00:08:07,159
the end of the session so that we uh can

172
00:08:07,159 --> 00:08:10,840
put our code onto our microbit so we

173
00:08:10,840 --> 00:08:12,919
will if I just show you on my screen let

174
00:08:12,919 --> 00:08:17,479
me get a view of me on the screen

175
00:08:17,560 --> 00:08:20,840
second so on the microbit here we will

176
00:08:20,840 --> 00:08:23,159
use the USB lead we will plug that into

177
00:08:23,159 --> 00:08:25,000
our computer and we'll plug the other

178
00:08:25,000 --> 00:08:26,960
end into our microbit and we will press

179
00:08:26,960 --> 00:08:28,560
download and we will put the code on the

180
00:08:28,560 --> 00:08:30,720
microbit and then attach the battery

181
00:08:30,720 --> 00:08:32,560
pack so that we can bring it outside

182
00:08:32,560 --> 00:08:36,320
into the environment and uh code and use

183
00:08:36,320 --> 00:08:40,279
the code we have created that way okay

184
00:08:40,279 --> 00:08:42,800
so coming back to our project that we're

185
00:08:42,800 --> 00:08:45,839
going to create today um I'm going to

186
00:08:45,839 --> 00:08:48,399
stop here and have a little think about

187
00:08:48,399 --> 00:08:51,480
what my program is going to do I want to

188
00:08:51,480 --> 00:08:54,560
use my microbit in the playground ler to

189
00:08:54,560 --> 00:08:57,279
count two different things the number of

190
00:08:57,279 --> 00:08:59,200
animal species and the number of plant

191
00:08:59,200 --> 00:09:01,560
species species I want the microbit to

192
00:09:01,560 --> 00:09:03,880
count for me and remember how many of

193
00:09:03,880 --> 00:09:05,200
these species I spotted because there's

194
00:09:05,200 --> 00:09:06,800
absolutely no way I'm going to keep all

195
00:09:06,800 --> 00:09:09,680
that information in my head so I want

196
00:09:09,680 --> 00:09:11,640
the microbit to remember the information

197
00:09:11,640 --> 00:09:14,079
or the data so that means I need to

198
00:09:14,079 --> 00:09:17,800
create two different variables so in the

199
00:09:17,800 --> 00:09:21,160
toolbox here we've got variables as a

200
00:09:21,160 --> 00:09:24,320
red menu section of the menu so if I

201
00:09:24,320 --> 00:09:26,680
click on variables you'll see it gives

202
00:09:26,680 --> 00:09:28,720
me one option right now and that is to

203
00:09:28,720 --> 00:09:31,240
make a variable able so variables are

204
00:09:31,240 --> 00:09:33,000
like containers they will hold different

205
00:09:33,000 --> 00:09:34,680
pieces of information and they will keep

206
00:09:34,680 --> 00:09:37,160
updating as we use the microbit and add

207
00:09:37,160 --> 00:09:38,120
more

208
00:09:38,120 --> 00:09:41,240
information so the two uh variables I

209
00:09:41,240 --> 00:09:44,120
want to create today are I click on make

210
00:09:44,120 --> 00:09:45,640
a variable and then I name them so I'm

211
00:09:45,640 --> 00:09:48,200
going to call my first one animal

212
00:09:48,200 --> 00:09:51,399
species and click okay and then I'm

213
00:09:51,399 --> 00:09:53,519
going to oh you see straight away some

214
00:09:53,519 --> 00:09:56,079
Co some blocks of code have appeared

215
00:09:56,079 --> 00:09:57,519
because I've created this variable so

216
00:09:57,519 --> 00:09:58,880
we've got some other blocks of code here

217
00:09:58,880 --> 00:10:02,160
we can use later and then I click on

218
00:10:02,160 --> 00:10:03,920
make a variable again and I'm going to

219
00:10:03,920 --> 00:10:05,880
call this plant

220
00:10:05,880 --> 00:10:09,880
species and click on okay so now I've

221
00:10:09,880 --> 00:10:14,000
got options to use these blocks of code

222
00:10:14,000 --> 00:10:17,640
to change it from animal to plant when I

223
00:10:17,640 --> 00:10:20,320
need it and I've made my two variables

224
00:10:20,320 --> 00:10:21,959
if I go back into variables here I can

225
00:10:21,959 --> 00:10:23,800
see them sitting here animal species and

226
00:10:23,800 --> 00:10:24,880
plant

227
00:10:24,880 --> 00:10:28,000
species okay so let me just delete that

228
00:10:28,000 --> 00:10:31,040
properly there we go

229
00:10:31,040 --> 00:10:34,240
so everyone approaches coding a little

230
00:10:34,240 --> 00:10:35,959
bit differently and sometimes there are

231
00:10:35,959 --> 00:10:37,440
different ways to achieve the same

232
00:10:37,440 --> 00:10:39,920
things so Giles what would you do next

233
00:10:39,920 --> 00:10:41,880
now that we've created the variables

234
00:10:41,880 --> 00:10:43,320
well I was just thinking about that when

235
00:10:43,320 --> 00:10:45,800
I turn on my mic a bit and the program

236
00:10:45,800 --> 00:10:49,320
starts I won't have counted any Vari I

237
00:10:49,320 --> 00:10:51,200
won't have counted any animal species or

238
00:10:51,200 --> 00:10:53,920
plant species yet so I'm thinking

239
00:10:53,920 --> 00:10:56,760
whether it's a good idea to set both

240
00:10:56,760 --> 00:11:00,240
variables to zero so what I might do is

241
00:11:00,240 --> 00:11:03,320
I might go into the variables

242
00:11:03,320 --> 00:11:07,560
menu and take set plant species to zero

243
00:11:07,560 --> 00:11:11,079
and drag that into the on block anything

244
00:11:11,079 --> 00:11:13,760
you put in the onstart block will um the

245
00:11:13,760 --> 00:11:15,880
microbit will carry out that instruction

246
00:11:15,880 --> 00:11:17,639
when the program starts running so it's

247
00:11:17,639 --> 00:11:20,320
going to set the zero uh set the plant

248
00:11:20,320 --> 00:11:22,480
species to zero at the start of the

249
00:11:22,480 --> 00:11:25,959
program then I drag the same block again

250
00:11:25,959 --> 00:11:29,040
so I go back into variables and drag out

251
00:11:29,040 --> 00:11:31,360
set plant species to zero again but I'm

252
00:11:31,360 --> 00:11:35,040
going to change maybe plant species to

253
00:11:35,040 --> 00:11:36,120
animal

254
00:11:36,120 --> 00:11:39,480
species so we have plant species and

255
00:11:39,480 --> 00:11:41,720
animal species both set to zero at the

256
00:11:41,720 --> 00:11:43,320
start of the program do you think that's

257
00:11:43,320 --> 00:11:46,600
a good idea blet yes definitely I would

258
00:11:46,600 --> 00:11:48,160
I would have done the same thing at this

259
00:11:48,160 --> 00:11:50,000
point for sure to make sure that the

260
00:11:50,000 --> 00:11:51,920
microbit knows to start counting from

261
00:11:51,920 --> 00:11:54,519
zero for each of those variables there's

262
00:11:54,519 --> 00:11:56,760
one other thing I do as well um there's

263
00:11:56,760 --> 00:11:58,720
nothing on the screen of the microbit

264
00:11:58,720 --> 00:12:00,680
when you turn on at the moment and I

265
00:12:00,680 --> 00:12:02,639
think it would be useful to also show a

266
00:12:02,639 --> 00:12:04,959
zero on the screen so I'm going to add

267
00:12:04,959 --> 00:12:07,519
in that instruction I'm going to go into

268
00:12:07,519 --> 00:12:10,600
the basic menu so the menus are all

269
00:12:10,600 --> 00:12:13,279
colorcoded and blue blocks are from the

270
00:12:13,279 --> 00:12:15,399
basic menu I'm going to take the first

271
00:12:15,399 --> 00:12:17,720
one here show number and I'm going to

272
00:12:17,720 --> 00:12:20,800
drag that in to the onart block here

273
00:12:20,800 --> 00:12:23,000
it's already got the number zero in it

274
00:12:23,000 --> 00:12:25,120
and now you can see the simulator has

275
00:12:25,120 --> 00:12:27,720
updated and when my mic bit starts it

276
00:12:27,720 --> 00:12:31,600
will show a zero on the screen as well

277
00:12:31,600 --> 00:12:34,040
okay so let's have a quick recap to to

278
00:12:34,040 --> 00:12:35,680
make sure that everyone is keeping up

279
00:12:35,680 --> 00:12:37,560
when they're coding along in their

280
00:12:37,560 --> 00:12:40,000
classrooms so have you made your

281
00:12:40,000 --> 00:12:41,920
variables remember we went into

282
00:12:41,920 --> 00:12:44,320
variables we clicked make a variable and

283
00:12:44,320 --> 00:12:46,720
we made two one called animal species

284
00:12:46,720 --> 00:12:50,120
and one called plant species okay have

285
00:12:50,120 --> 00:12:52,800
you set your variables to zero we took

286
00:12:52,800 --> 00:12:55,600
out this one set plant species to zero

287
00:12:55,600 --> 00:12:56,959
and we used it

288
00:12:56,959 --> 00:12:59,480
twice but we changed it using the drop

289
00:12:59,480 --> 00:13:01,399
down menu from plant species to animal

290
00:13:01,399 --> 00:13:04,920
species and we popped that into the

291
00:13:04,920 --> 00:13:07,880
onstart block and then we added a zero

292
00:13:07,880 --> 00:13:09,959
through using the show Number Block here

293
00:13:09,959 --> 00:13:14,720
in the basic menu as well okay

294
00:13:14,720 --> 00:13:16,639
so that

295
00:13:16,639 --> 00:13:20,519
means we have got started but there's

296
00:13:20,519 --> 00:13:23,440
two very important things that we need

297
00:13:23,440 --> 00:13:25,920
to do next and they're both to do with

298
00:13:25,920 --> 00:13:28,079
using the buttons on the microbit

299
00:13:28,079 --> 00:13:29,480
because we're going to be using both

300
00:13:29,480 --> 00:13:33,079
button a and button B uh that are on the

301
00:13:33,079 --> 00:13:35,600
front of the microbit so we're going to

302
00:13:35,600 --> 00:13:37,880
use one button to log data about animal

303
00:13:37,880 --> 00:13:39,760
species and we're going to use another

304
00:13:39,760 --> 00:13:41,680
button to log the data about plant

305
00:13:41,680 --> 00:13:45,959
species so let's start with button a

306
00:13:45,959 --> 00:13:48,079
here are a few

307
00:13:48,079 --> 00:13:52,160
clues for what we're going to

308
00:13:52,160 --> 00:13:54,880
use button a for any

309
00:13:54,880 --> 00:13:59,880
ideas well um let me see we had uh a

310
00:13:59,880 --> 00:14:03,040
butterfly we've had uh a bird and a

311
00:14:03,040 --> 00:14:07,040
snail so I think a is going to be for

312
00:14:07,040 --> 00:14:10,560
Animals correct yes A is for Animals is

313
00:14:10,560 --> 00:14:13,360
animals that's easy to remember yes so

314
00:14:13,360 --> 00:14:15,480
all the pictures are animals so button a

315
00:14:15,480 --> 00:14:18,240
is going to lck the animal species so to

316
00:14:18,240 --> 00:14:19,800
make something happen on the micob bit

317
00:14:19,800 --> 00:14:22,240
when we press button a we will need the

318
00:14:22,240 --> 00:14:24,680
on button a press block so you'll find

319
00:14:24,680 --> 00:14:26,959
this in a new menu the the purple

320
00:14:26,959 --> 00:14:29,839
purpley pink menu here called

321
00:14:29,839 --> 00:14:32,600
if I go into that menu the very first

322
00:14:32,600 --> 00:14:35,040
block is on button a press so let's pull

323
00:14:35,040 --> 00:14:37,360
that out and put that into the

324
00:14:37,360 --> 00:14:41,040
workspace okay so we want the animal

325
00:14:41,040 --> 00:14:44,320
species uh variable to update by one

326
00:14:44,320 --> 00:14:47,480
each time we press button a so that

327
00:14:47,480 --> 00:14:49,000
means I need to go back into my

328
00:14:49,000 --> 00:14:52,759
variables menu in here and I I'm looking

329
00:14:52,759 --> 00:14:55,160
at the second block here I want to

330
00:14:55,160 --> 00:14:57,639
change something by one when I press

331
00:14:57,639 --> 00:15:00,920
button a now when I pull this out just

332
00:15:00,920 --> 00:15:02,920
pop it there for a moment it it goes

333
00:15:02,920 --> 00:15:04,240
this strange color because it's not

334
00:15:04,240 --> 00:15:07,079
inside uh a working block at the moment

335
00:15:07,079 --> 00:15:09,000
but I can still manipulate it here I can

336
00:15:09,000 --> 00:15:10,720
still change it to what I want so I

337
00:15:10,720 --> 00:15:12,600
actually want to change the animal

338
00:15:12,600 --> 00:15:14,839
species on but a so I'm going to switch

339
00:15:14,839 --> 00:15:17,759
that to animal species and I pop it

340
00:15:17,759 --> 00:15:22,240
inside the on button a pressed block so

341
00:15:22,240 --> 00:15:25,040
that means that the microbit will update

342
00:15:25,040 --> 00:15:27,079
the total number of animal

343
00:15:27,079 --> 00:15:31,720
species each time we press button a uh

344
00:15:31,720 --> 00:15:34,720
on the micro bit

345
00:15:34,759 --> 00:15:37,959
itself okay Planet I I got a question

346
00:15:37,959 --> 00:15:40,000
here I I've been following along I've

347
00:15:40,000 --> 00:15:41,880
got the same blocks as you but when I

348
00:15:41,880 --> 00:15:45,560
press button a I just get zero on the

349
00:15:45,560 --> 00:15:47,839
screen even though I keep pressing

350
00:15:47,839 --> 00:15:50,639
button a have I done something wrong not

351
00:15:50,639 --> 00:15:53,680
at all Giles um

352
00:15:53,680 --> 00:15:56,560
I I have the same thing happening on my

353
00:15:56,560 --> 00:16:00,440
mic bit on here so I might be pressing

354
00:16:00,440 --> 00:16:02,519
on my simulator I might press butt a a

355
00:16:02,519 --> 00:16:04,240
couple of times but my screen has not

356
00:16:04,240 --> 00:16:06,639
changed so you have not done anything

357
00:16:06,639 --> 00:16:09,839
wrong you just have not given the

358
00:16:09,839 --> 00:16:12,120
microbit the instructions to do that

359
00:16:12,120 --> 00:16:15,560
part yet okay the micr will only do what

360
00:16:15,560 --> 00:16:18,160
you ask it to do if we want to see the

361
00:16:18,160 --> 00:16:20,839
total on the LED display then we need to

362
00:16:20,839 --> 00:16:22,360
put those instructions in and ask the

363
00:16:22,360 --> 00:16:24,120
microbit to show it to us so let's add a

364
00:16:24,120 --> 00:16:26,000
few more blocks to make that

365
00:16:26,000 --> 00:16:30,880
happen so if we go into to um what are

366
00:16:30,880 --> 00:16:32,440
we going to go we're going to go into

367
00:16:32,440 --> 00:16:35,519
into basic first of all and we're going

368
00:16:35,519 --> 00:16:39,399
to scroll down to the show icon block

369
00:16:39,399 --> 00:16:42,319
okay so this will help us know that when

370
00:16:42,319 --> 00:16:44,600
it shows us data on the LED display it's

371
00:16:44,600 --> 00:16:48,839
talking about animal species data so I'm

372
00:16:48,839 --> 00:16:51,440
going to pop that in here and I'm going

373
00:16:51,440 --> 00:16:53,639
to change the icon from a heart to

374
00:16:53,639 --> 00:16:55,480
something that resembles an animal

375
00:16:55,480 --> 00:16:57,920
species so let's have a look got lots of

376
00:16:57,920 --> 00:17:00,240
pre-prepared icons here right I'm going

377
00:17:00,240 --> 00:17:02,680
to choose the duck so we've got a little

378
00:17:02,680 --> 00:17:06,559
duck icon to to stand for our animal

379
00:17:06,559 --> 00:17:09,640
species right um the next thing I'm

380
00:17:09,640 --> 00:17:11,360
going to do is I'm going to go back into

381
00:17:11,360 --> 00:17:13,280
basic and I'm going to take the show

382
00:17:13,280 --> 00:17:15,439
number block again and I'm going to pop

383
00:17:15,439 --> 00:17:18,400
it in below now this time I don't want

384
00:17:18,400 --> 00:17:21,160
to the show Number Block to show us zero

385
00:17:21,160 --> 00:17:23,199
I want it to show the total number of

386
00:17:23,199 --> 00:17:25,880
animal species on the LED display so

387
00:17:25,880 --> 00:17:29,039
I've got to go back into variables and

388
00:17:29,039 --> 00:17:31,520
find my animal species block the small

389
00:17:31,520 --> 00:17:34,440
one here so I take this out and you can

390
00:17:34,440 --> 00:17:37,720
see how it can slot in over the zero and

391
00:17:37,720 --> 00:17:41,280
replace it so we do that and then our

392
00:17:41,280 --> 00:17:43,039
code will

393
00:17:43,039 --> 00:17:46,520
update okay so now if we test if it's

394
00:17:46,520 --> 00:17:48,679
working on the simulator it should work

395
00:17:48,679 --> 00:17:51,000
this time but actually I've got an idea

396
00:17:51,000 --> 00:17:53,880
to test that Giles so do you remember

397
00:17:53,880 --> 00:17:57,000
this this slide that we looked at

398
00:17:57,000 --> 00:18:01,320
earlier oh yeah was it again how many

399
00:18:01,320 --> 00:18:03,559
times I press a if these were the

400
00:18:03,559 --> 00:18:06,080
animals I'd seen outside oh gosh right

401
00:18:06,080 --> 00:18:07,960
I'm trying to remember again we had

402
00:18:07,960 --> 00:18:11,320
snails and uh that was one species and

403
00:18:11,320 --> 00:18:12,919
then we had two butterflies but that's

404
00:18:12,919 --> 00:18:14,520
only one more species because they're

405
00:18:14,520 --> 00:18:17,000
both both the same species so that's one

406
00:18:17,000 --> 00:18:21,240
more uh we had a bird and we've got a

407
00:18:21,240 --> 00:18:23,440
fly and I've got a worm so I think it

408
00:18:23,440 --> 00:18:26,159
was five different animal species that

409
00:18:26,159 --> 00:18:29,840
we have there correct well done J yes so

410
00:18:29,840 --> 00:18:33,159
on my simulator now I am going to press

411
00:18:33,159 --> 00:18:35,400
a five times and let's see if we can see

412
00:18:35,400 --> 00:18:38,039
something happening and

413
00:18:38,039 --> 00:18:44,120
see yes there we go one two 3

414
00:18:44,120 --> 00:18:47,039
4 five so we've now given the correct

415
00:18:47,039 --> 00:18:49,080
instructions yeah so we can see now that

416
00:18:49,080 --> 00:18:50,919
when we log one it will give us some

417
00:18:50,919 --> 00:18:52,960
feedback on the LED display to know that

418
00:18:52,960 --> 00:18:56,919
it's happened um so if everyone has got

419
00:18:56,919 --> 00:19:00,799
this part coded then that means we are

420
00:19:00,799 --> 00:19:04,360
halfway there

421
00:19:05,480 --> 00:19:07,280
yay

422
00:19:07,280 --> 00:19:10,360
fantastic fantastic so we're halfway

423
00:19:10,360 --> 00:19:12,799
there um and we've told the microb bit

424
00:19:12,799 --> 00:19:14,400
what to do when we press button a when

425
00:19:14,400 --> 00:19:17,480
we're counting animal species but we

426
00:19:17,480 --> 00:19:20,600
haven't yet told it what to do when we

427
00:19:20,600 --> 00:19:24,320
press button B now I wonder if anyone

428
00:19:24,320 --> 00:19:27,600
can remember what are we going to count

429
00:19:27,600 --> 00:19:30,000
when we press but button B can anyone

430
00:19:30,000 --> 00:19:31,760
remember that

431
00:19:31,760 --> 00:19:36,360
I ah right so we've got uh some flowers

432
00:19:36,360 --> 00:19:37,840
we've got a

433
00:19:37,840 --> 00:19:43,640
tree um oh and some more plants oh is it

434
00:19:43,640 --> 00:19:45,159
plant species

435
00:19:45,159 --> 00:19:48,000
Jiles might be plant species that we're

436
00:19:48,000 --> 00:19:49,640
getting when we press button

437
00:19:49,640 --> 00:19:52,240
D so what we want to do is we want to

438
00:19:52,240 --> 00:19:55,640
use button B to to log plant species so

439
00:19:55,640 --> 00:19:59,840
what we can do now is we can dup at or

440
00:19:59,840 --> 00:20:02,960
copy the blocks that we have for button

441
00:20:02,960 --> 00:20:04,880
a I wonder bled could you show us how to

442
00:20:04,880 --> 00:20:05,960
do

443
00:20:05,960 --> 00:20:07,960
that what do you can you just tell us

444
00:20:07,960 --> 00:20:09,640
what you're doing there to get that that

445
00:20:09,640 --> 00:20:12,240
menu to pop up yeah so I've put my

446
00:20:12,240 --> 00:20:15,360
cursor over the entire block on button a

447
00:20:15,360 --> 00:20:17,520
pressed and then I've right clicked and

448
00:20:17,520 --> 00:20:19,520
then I get the menu at duplicate at the

449
00:20:19,520 --> 00:20:21,240
top so you can duplicate that's one way

450
00:20:21,240 --> 00:20:22,919
of doing it or you can just fetch the

451
00:20:22,919 --> 00:20:25,360
blocks again uh from the toolbox in the

452
00:20:25,360 --> 00:20:27,000
middle but just because it's quicker and

453
00:20:27,000 --> 00:20:28,840
easier we're going to show you uh how to

454
00:20:28,840 --> 00:20:30,600
duplicate so if you click on that and

455
00:20:30,600 --> 00:20:32,720
duplicate the block you'll see again

456
00:20:32,720 --> 00:20:34,440
like a bit like it did before the blocks

457
00:20:34,440 --> 00:20:36,559
have gone a funny color uh and that's

458
00:20:36,559 --> 00:20:39,520
because we've got two on button a press

459
00:20:39,520 --> 00:20:41,919
blocks and we can only have one uh set

460
00:20:41,919 --> 00:20:43,960
of instructions for what to do when you

461
00:20:43,960 --> 00:20:45,679
press button a otherwise the microbit

462
00:20:45,679 --> 00:20:48,159
will get really confused so first thing

463
00:20:48,159 --> 00:20:51,360
we need to do is to change button a to

464
00:20:51,360 --> 00:20:55,919
button B okay and then because we're not

465
00:20:55,919 --> 00:20:57,720
counting animal species anymore we need

466
00:20:57,720 --> 00:21:01,159
to change animal species to plant

467
00:21:01,159 --> 00:21:03,080
species and I think it would be a good

468
00:21:03,080 --> 00:21:05,280
idea to show a different picture at this

469
00:21:05,280 --> 00:21:07,480
point not a duck so we'll pick something

470
00:21:07,480 --> 00:21:09,760
else so if you click on that have a look

471
00:21:09,760 --> 00:21:11,760
and pick something there is I think

472
00:21:11,760 --> 00:21:13,960
there's a fork icon that looks a little

473
00:21:13,960 --> 00:21:17,279
bit like a tree that's it that one we

474
00:21:17,279 --> 00:21:19,919
can pick that you can also draw your own

475
00:21:19,919 --> 00:21:21,640
plant icon as well if you like you can

476
00:21:21,640 --> 00:21:24,360
use the show LEDs Block in the basic

477
00:21:24,360 --> 00:21:25,840
category and you can draw your own

478
00:21:25,840 --> 00:21:27,880
picture of an animal or a plant but

479
00:21:27,880 --> 00:21:29,480
we're just going to pick the the fork

480
00:21:29,480 --> 00:21:32,039
icon because it looks a bit like a tree

481
00:21:32,039 --> 00:21:33,799
uh and then I think there's one more

482
00:21:33,799 --> 00:21:35,440
thing we need to change yeah well

483
00:21:35,440 --> 00:21:37,240
spotted bled because at the moment the

484
00:21:37,240 --> 00:21:39,159
code is going to show the animal species

485
00:21:39,159 --> 00:21:40,720
number when we press button B and that

486
00:21:40,720 --> 00:21:42,600
would be wrong so we need to click on

487
00:21:42,600 --> 00:21:45,640
the little arrow on that and change that

488
00:21:45,640 --> 00:21:48,120
to plant

489
00:21:48,120 --> 00:21:49,640
species

490
00:21:49,640 --> 00:21:52,039
perfect thank you Giles I think that's

491
00:21:52,039 --> 00:21:53,520
looking like it should work really well

492
00:21:53,520 --> 00:21:55,320
and we should be able to test out button

493
00:21:55,320 --> 00:22:00,679
B on the simulator now as well um so if

494
00:22:00,679 --> 00:22:04,159
I was outside and these were all the

495
00:22:04,159 --> 00:22:06,159
plants I saw while I was in my

496
00:22:06,159 --> 00:22:09,240
playground how many plant species would

497
00:22:09,240 --> 00:22:12,120
I log how many times do I press button B

498
00:22:12,120 --> 00:22:13,600
oh that's a good question because I can

499
00:22:13,600 --> 00:22:15,400
see lots of flowers there so I might

500
00:22:15,400 --> 00:22:18,200
want to keep clicking uh and click lots

501
00:22:18,200 --> 00:22:19,799
of flowers but I need to think I need to

502
00:22:19,799 --> 00:22:22,240
be really careful about this I think

503
00:22:22,240 --> 00:22:24,480
there are only two species here because

504
00:22:24,480 --> 00:22:26,960
I've got flowers like daisies they look

505
00:22:26,960 --> 00:22:28,520
the same so although there's lots of FL

506
00:22:28,520 --> 00:22:31,159
flowers there that's only one species

507
00:22:31,159 --> 00:22:33,120
that I've spotted and then there's some

508
00:22:33,120 --> 00:22:35,240
Ivy some leaves growing in the middle so

509
00:22:35,240 --> 00:22:37,720
I think here if I saw that when I went

510
00:22:37,720 --> 00:22:40,720
outside I would log two plant species I

511
00:22:40,720 --> 00:22:44,279
would press button B twice fantastic

512
00:22:44,279 --> 00:22:46,559
that is very accurate and correct so I'm

513
00:22:46,559 --> 00:22:51,679
going to do button B twice now on my

514
00:22:51,679 --> 00:22:54,000
simulator and there we go we can see the

515
00:22:54,000 --> 00:22:56,240
plant icon came up and the number came

516
00:22:56,240 --> 00:22:57,919
up each time as well which is exactly

517
00:22:57,919 --> 00:23:00,919
what we've asked it to do using the code

518
00:23:00,919 --> 00:23:03,360
so that's that's fantastic Planet that's

519
00:23:03,360 --> 00:23:05,600
really good but the number just flashes

520
00:23:05,600 --> 00:23:10,440
up what if I can't remember the number

521
00:23:10,440 --> 00:23:13,240
of animal species and plant species is

522
00:23:13,240 --> 00:23:15,559
there a way we can get to see the the

523
00:23:15,559 --> 00:23:18,039
sort of running total without having to

524
00:23:18,039 --> 00:23:20,720
add a new one each time yeah that's a

525
00:23:20,720 --> 00:23:21,960
really good point because I can't

526
00:23:21,960 --> 00:23:23,559
remember now even how many animal

527
00:23:23,559 --> 00:23:25,120
species we'd already logged a few

528
00:23:25,120 --> 00:23:28,159
minutes ago so we definitely need to to

529
00:23:28,159 --> 00:23:30,039
to add that in because we don't want to

530
00:23:30,039 --> 00:23:33,799
get our numbers muddled up so um let's

531
00:23:33,799 --> 00:23:35,919
use the icons again to make it clear

532
00:23:35,919 --> 00:23:37,919
which total is coming up on the LED

533
00:23:37,919 --> 00:23:42,039
display but let's also um use a new

534
00:23:42,039 --> 00:23:43,720
input so we've used button a and we've

535
00:23:43,720 --> 00:23:46,600
used button B to do our actual logging

536
00:23:46,600 --> 00:23:49,640
but now let's use the touch logo on the

537
00:23:49,640 --> 00:23:51,679
front of the microbit as the input to

538
00:23:51,679 --> 00:23:54,080
show us our totals so you'll find that

539
00:23:54,080 --> 00:23:56,880
in the inputs menu and if you scroll

540
00:23:56,880 --> 00:23:59,440
right down past where it says microbit

541
00:23:59,440 --> 00:24:03,120
V2 right down here we get the on Logo

542
00:24:03,120 --> 00:24:05,919
pressed block so if I pull that out now

543
00:24:05,919 --> 00:24:10,600
I'm going to use this as my input now I

544
00:24:10,600 --> 00:24:12,799
said we wanted to use the icons again so

545
00:24:12,799 --> 00:24:14,279
that's the next time we're going next

546
00:24:14,279 --> 00:24:15,279
thing we're going to do we're going to

547
00:24:15,279 --> 00:24:17,840
go to basic we're going to drag out our

548
00:24:17,840 --> 00:24:20,799
show icon pop it in here and I'm going

549
00:24:20,799 --> 00:24:23,640
to change this one to the animal icon

550
00:24:23,640 --> 00:24:24,919
we' selected

551
00:24:24,919 --> 00:24:28,360
earlier and then I want to show my total

552
00:24:28,360 --> 00:24:31,159
to Al number of animal species counted

553
00:24:31,159 --> 00:24:34,240
so if I go back into basic take show

554
00:24:34,240 --> 00:24:38,080
number pop it in and then I find my

555
00:24:38,080 --> 00:24:40,240
variable my animal species variable in

556
00:24:40,240 --> 00:24:43,320
the variables menu pull that out and

557
00:24:43,320 --> 00:24:46,880
that goes on top so that means when you

558
00:24:46,880 --> 00:24:49,600
press the logo the duck icon will will

559
00:24:49,600 --> 00:24:51,760
come up and then the total number of

560
00:24:51,760 --> 00:24:54,480
animal species now I also want to to see

561
00:24:54,480 --> 00:24:55,919
the plant species but I don't want it

562
00:24:55,919 --> 00:24:58,520
all to happen too quickly it needs to be

563
00:24:58,520 --> 00:25:00,279
clear when we read it off the screen and

564
00:25:00,279 --> 00:25:02,360
then when there's numbers that are

565
00:25:02,360 --> 00:25:04,799
two-digit or even three-digit numbers

566
00:25:04,799 --> 00:25:06,720
they will scroll so we need a little bit

567
00:25:06,720 --> 00:25:09,159
of time for the microbit to do its thing

568
00:25:09,159 --> 00:25:11,760
so we're going to leave a small pause so

569
00:25:11,760 --> 00:25:15,480
if I go back into basic and scroll down

570
00:25:15,480 --> 00:25:18,120
find the pause block I'm going to pop

571
00:25:18,120 --> 00:25:21,520
that in and let's pause for two

572
00:25:21,520 --> 00:25:24,080
seconds that shows up as 2,000

573
00:25:24,080 --> 00:25:27,000
milliseconds on the Block and then I'm

574
00:25:27,000 --> 00:25:28,799
going to go back into basic and another

575
00:25:28,799 --> 00:25:30,720
time and I'm going to get the clear

576
00:25:30,720 --> 00:25:33,200
screen block here so that clean the

577
00:25:33,200 --> 00:25:35,840
screen goes completely clear before it

578
00:25:35,840 --> 00:25:37,240
me any of the

579
00:25:37,240 --> 00:25:41,720
plant species data so now I want to show

580
00:25:41,720 --> 00:25:43,799
the plant species data actually I'll

581
00:25:43,799 --> 00:25:45,760
just do one more pause before that so

582
00:25:45,760 --> 00:25:47,679
I'm going to duplicate that block be

583
00:25:47,679 --> 00:25:50,000
doubly sure that the screen clears and

584
00:25:50,000 --> 00:25:54,120
has time to clear now back into basic

585
00:25:54,120 --> 00:25:57,880
take your show icon change that to our

586
00:25:57,880 --> 00:26:02,640
tree like icon here go back into basic

587
00:26:02,640 --> 00:26:06,080
take another show number and this time

588
00:26:06,080 --> 00:26:08,559
in the variables menu I choose plant

589
00:26:08,559 --> 00:26:14,159
species and put it in there so hopefully

590
00:26:14,159 --> 00:26:16,080
that will have given the microbit the

591
00:26:16,080 --> 00:26:18,679
instructions needed for us to see the

592
00:26:18,679 --> 00:26:22,559
totals on the screen when we want to to

593
00:26:22,559 --> 00:26:24,919
recap how many we've counted of each so

594
00:26:24,919 --> 00:26:26,679
shall we try out on the simulator now

595
00:26:26,679 --> 00:26:28,559
Giles I think that sounds like a really

596
00:26:28,559 --> 00:26:30,000
good idea right I'm going to put you to

597
00:26:30,000 --> 00:26:32,559
the test I'm going to show you some

598
00:26:32,559 --> 00:26:34,840
pictures and see if you can count along

599
00:26:34,840 --> 00:26:36,880
and correctly count the species I'm

600
00:26:36,880 --> 00:26:40,000
going to reset my microb bit first just

601
00:26:40,000 --> 00:26:41,760
clear any of the data we've done so far

602
00:26:41,760 --> 00:26:42,799
so you would do that on the real

603
00:26:42,799 --> 00:26:44,120
microbit with the reset button on the

604
00:26:44,120 --> 00:26:45,880
back but I've just pressed this uh

605
00:26:45,880 --> 00:26:49,080
symbol here on the simulator okay test

606
00:26:49,080 --> 00:26:51,720
me fantastic are you ready yes okay here

607
00:26:51,720 --> 00:26:54,840
we go that's a tree so that's a plant

608
00:26:54,840 --> 00:26:57,159
species so that's one plant species so

609
00:26:57,159 --> 00:26:59,559
far oh that's another tree so hang on I

610
00:26:59,559 --> 00:27:02,159
need to have pressed B once but not

611
00:27:02,159 --> 00:27:04,520
again because they're the same species

612
00:27:04,520 --> 00:27:08,080
well done okay let's try one more right

613
00:27:08,080 --> 00:27:09,840
that's a different plant species so I'm

614
00:27:09,840 --> 00:27:12,080
going to press B again that's the second

615
00:27:12,080 --> 00:27:14,880
plant species I've

616
00:27:15,000 --> 00:27:17,679
seen there's our lovely Robin that's a

617
00:27:17,679 --> 00:27:21,159
animal species a bird

618
00:27:21,159 --> 00:27:25,320
okay and I'll give you one more okay

619
00:27:25,320 --> 00:27:26,799
fantastic that's

620
00:27:26,799 --> 00:27:31,080
another animal species so let's see if I

621
00:27:31,080 --> 00:27:34,840
go to my touch logo and I click this now

622
00:27:34,840 --> 00:27:36,000
let's see what

623
00:27:36,000 --> 00:27:38,039
happens animals

624
00:27:38,039 --> 00:27:41,159
to should clear the screen there a

625
00:27:41,159 --> 00:27:44,720
little pause there two fantastic

626
00:27:44,720 --> 00:27:49,200
fantastic well done woohoo so that's it

627
00:27:49,200 --> 00:27:51,640
if you have got this far with us you

628
00:27:51,640 --> 00:27:54,679
have now coded your biodiversity code

629
00:27:54,679 --> 00:27:57,240
along uh biodiversity counter I should

630
00:27:57,240 --> 00:28:01,060
say that you can use outside in your

631
00:28:01,060 --> 00:28:07,200
[Applause]

632
00:28:07,200 --> 00:28:09,519
playground two lots of Applause and

633
00:28:09,519 --> 00:28:11,519
cheering that's marvelous so once you

634
00:28:11,519 --> 00:28:15,159
know the number of the current number of

635
00:28:15,159 --> 00:28:17,440
animal and plant species you could

636
00:28:17,440 --> 00:28:19,720
monitor whether this changes over time

637
00:28:19,720 --> 00:28:21,039
because you could count them again in

638
00:28:21,039 --> 00:28:23,679
the future um you might want to try some

639
00:28:23,679 --> 00:28:25,640
things in your local environment to

640
00:28:25,640 --> 00:28:27,880
improve biodiversity and see if you get

641
00:28:27,880 --> 00:28:29,480
better better numbers next time if you

642
00:28:29,480 --> 00:28:31,840
get a more diverse environment with

643
00:28:31,840 --> 00:28:34,200
different more different kinds of

644
00:28:34,200 --> 00:28:36,320
plants and there's lots of other things

645
00:28:36,320 --> 00:28:37,840
you can do with that data that you go

646
00:28:37,840 --> 00:28:40,519
outside and collect you could present it

647
00:28:40,519 --> 00:28:43,120
in bar charts or other kinds of graphs

648
00:28:43,120 --> 00:28:45,399
tally charts you could share your

649
00:28:45,399 --> 00:28:47,159
findings with other classes in your

650
00:28:47,159 --> 00:28:49,559
school or you could compare your

651
00:28:49,559 --> 00:28:51,600
playground to other outdoor environments

652
00:28:51,600 --> 00:28:55,919
such as Parks or maybe even another

653
00:28:55,919 --> 00:28:58,919
school fabulous so thank you for those

654
00:28:58,919 --> 00:29:01,640
ideas Giles they're really useful we we

655
00:29:01,640 --> 00:29:03,640
have finished coding but there is one

656
00:29:03,640 --> 00:29:06,320
more really important thing to do you

657
00:29:06,320 --> 00:29:09,880
need to transfer the code to your real

658
00:29:09,880 --> 00:29:11,880
life microbit so you can use it to count

659
00:29:11,880 --> 00:29:14,360
biodiversity in your playground outside

660
00:29:14,360 --> 00:29:16,559
or another outside area so what we're

661
00:29:16,559 --> 00:29:19,320
going to do is we're going to um use the

662
00:29:19,320 --> 00:29:23,600
USB cable to plug our mic bits into the

663
00:29:23,600 --> 00:29:25,559
computer or laptop that you've been

664
00:29:25,559 --> 00:29:28,120
using now if you've been using tablets

665
00:29:28,120 --> 00:29:29,360
then obviously there's a different way

666
00:29:29,360 --> 00:29:32,159
to transfer the code um I won't demo

667
00:29:32,159 --> 00:29:34,960
that today but the link that is now

668
00:29:34,960 --> 00:29:36,880
showing on screen will give you all the

669
00:29:36,880 --> 00:29:38,919
different options for how to get code

670
00:29:38,919 --> 00:29:41,200
onto your microbit tablets included so

671
00:29:41,200 --> 00:29:43,039
you can have a look at that instead but

672
00:29:43,039 --> 00:29:45,799
I'll just do a very quick demo of how to

673
00:29:45,799 --> 00:29:48,440
get it on if you're using a laptop or a

674
00:29:48,440 --> 00:29:52,080
tablet or a um sorry a desktop computer

675
00:29:52,080 --> 00:29:56,240
so the small part of the USB cable goes

676
00:29:56,240 --> 00:29:58,480
into the top of the microbit so you can

677
00:29:58,480 --> 00:30:00,519
see there and then I'm going to plug

678
00:30:00,519 --> 00:30:01,640
this

679
00:30:01,640 --> 00:30:05,640
into my um my laptop that I'm using so

680
00:30:05,640 --> 00:30:08,519
I'm plugging it in here the USB end of

681
00:30:08,519 --> 00:30:12,159
it goes in okay now I'm just going to

682
00:30:12,159 --> 00:30:16,240
share my screen before I

683
00:30:16,240 --> 00:30:19,519
plug the rest of it in so one second

684
00:30:19,519 --> 00:30:23,760
stop there I'm going to go

685
00:30:23,760 --> 00:30:25,279
to

686
00:30:25,279 --> 00:30:29,240
this okay now if I do this this way and

687
00:30:29,240 --> 00:30:31,399
I get up my

688
00:30:31,399 --> 00:30:34,200
downloads you will see something appear

689
00:30:34,200 --> 00:30:36,200
in this menu on the left when I plug in

690
00:30:36,200 --> 00:30:37,080
my

691
00:30:37,080 --> 00:30:39,559
microbit so I've plugged it

692
00:30:39,559 --> 00:30:43,640
in keep an eye here Tada the microbit

693
00:30:43,640 --> 00:30:45,840
drive has appeared there because my mic

694
00:30:45,840 --> 00:30:47,960
bit has been plugged in so I know that

695
00:30:47,960 --> 00:30:51,039
it's connected and so now that I've

696
00:30:51,039 --> 00:30:54,559
plugged it in on my make code editor I

697
00:30:54,559 --> 00:30:56,360
need to click on the download button and

698
00:30:56,360 --> 00:30:58,600
follow the instructions on screen

699
00:30:58,600 --> 00:31:01,960
so I click that now download and it's

700
00:31:01,960 --> 00:31:03,519
downloading to my micro bit now if it's

701
00:31:03,519 --> 00:31:05,279
the first time you've downloaded it may

702
00:31:05,279 --> 00:31:07,440
ask you to pair it first but you simply

703
00:31:07,440 --> 00:31:09,480
follow the instructions on screen and it

704
00:31:09,480 --> 00:31:11,360
will then give you the option to

705
00:31:11,360 --> 00:31:13,760
download it if that doesn't work for any

706
00:31:13,760 --> 00:31:16,279
reason there's also a drag and drop

707
00:31:16,279 --> 00:31:18,760
method where if you download the hex

708
00:31:18,760 --> 00:31:21,720
file using the three dots next to the

709
00:31:21,720 --> 00:31:23,760
download button you can click on

710
00:31:23,760 --> 00:31:25,159
download as

711
00:31:25,159 --> 00:31:29,679
file okay that has now gone to my

712
00:31:29,679 --> 00:31:31,679
downloads you can see it here there's

713
00:31:31,679 --> 00:31:34,120
our project that we just made and I can

714
00:31:34,120 --> 00:31:36,480
now drag and drop that on top of my

715
00:31:36,480 --> 00:31:39,559
microbit drive and my microbit will

716
00:31:39,559 --> 00:31:41,200
start flashing on the back so I know

717
00:31:41,200 --> 00:31:42,639
that that's working as well so that's

718
00:31:42,639 --> 00:31:45,799
another way to get it on okay so once

719
00:31:45,799 --> 00:31:47,919
you've got it on there of course the

720
00:31:47,919 --> 00:31:49,840
next thing to do is to plug your battery

721
00:31:49,840 --> 00:31:53,919
pack in unplug it from your uh computer

722
00:31:53,919 --> 00:31:56,919
and then you can take it outside and get

723
00:31:56,919 --> 00:31:59,760
going with love the diversity all around

724
00:31:59,760 --> 00:32:02,559
