hello and welcome to our BBC microbic

0:00:40.879,0:00:44.440
Global codal my name is Giles and my

0:00:44.440,0:00:46.239
name is blaed and we are part of the

0:00:46.239,0:00:48.399
Education team here at the microbit

0:00:48.399,0:00:51.440
Educational Foundation now does anyone

0:00:51.440,0:00:55.079
know the theme of today's Cod along here

0:00:55.079,0:00:57.920
are a few

0:00:58.120,0:01:01.719
Clues there a butterfly

0:01:01.719,0:01:06.400
F uh oh okay that looks like some

0:01:06.400,0:01:10.400
flowers well that's definitely a

0:01:11.320,0:01:15.159
tree oh my goodness a very large Robin a

0:01:15.159,0:01:17.200
very large

0:01:17.200,0:01:20.479
bird so well done anyone watching if you

0:01:20.479,0:01:23.079
have shouted out the theme is

0:01:23.079,0:01:25.600
biodiversity happy International Day for

0:01:25.600,0:01:29.280
biological diversity um or International

0:01:29.280,0:01:31.040
Day for bio biodiversity as it can be

0:01:31.040,0:01:34.720
shortened to the United Nations theme uh

0:01:34.720,0:01:37.439
this year is all about building back

0:01:37.439,0:01:40.240
biodiversity because we all depend on a

0:01:40.240,0:01:46.040
wide variety of plants and animals and

0:01:46.040,0:01:48.880
microorganisms to keep us all healthy

0:01:48.880,0:01:52.360
and thriving so in today's codal along

0:01:52.360,0:01:54.600
you are going to be doing your bit as

0:01:54.600,0:01:56.039
well because you are going to be

0:01:56.039,0:01:58.960
building back bio biodiversity too by

0:01:58.960,0:02:01.680
creating a bi biodiversity counter that

0:02:01.680,0:02:03.920
can be used in your school playground or

0:02:03.920,0:02:06.320
any other outdoor area you have near

0:02:06.320,0:02:09.520
your school and as today is UN day for

0:02:09.520,0:02:12.599
biodiversity the plan is to create uh

0:02:12.599,0:02:15.720
the project in the make code editor but

0:02:15.720,0:02:17.640
then to transfer the code onto the

0:02:17.640,0:02:20.239
microbit and use them outside to count

0:02:20.239,0:02:22.000
the number of species of animals and

0:02:22.000,0:02:24.640
species of plants that you can spot you

0:02:24.640,0:02:26.560
don't need a microbit to take part in

0:02:26.560,0:02:28.519
this session as we will be making good

0:02:28.519,0:02:30.480
use of the simulator on make code

0:02:30.480,0:02:33.040
website but if you do have microbits

0:02:33.040,0:02:34.599
then make sure you have them out ready

0:02:34.599,0:02:36.720
to put the code on at the end of the

0:02:36.720,0:02:39.120
session and in today's session we're

0:02:39.120,0:02:41.560
going to be coding along together make

0:02:41.560,0:02:44.159
sure that you pause the video whenever

0:02:44.159,0:02:46.480
you need to and you can replay parts

0:02:46.480,0:02:49.640
that you need to hear over again I'm

0:02:49.640,0:02:51.200
really excited that we're coding the

0:02:51.200,0:02:53.440
biodiversity cter together so students

0:02:53.440,0:02:55.200
all over the world can see what their

0:02:55.200,0:02:58.519
local biodiversity is like if you have a

0:02:58.519,0:03:01.080
school Twitter or X account then make

0:03:01.080,0:03:05.040
sure you share how you get on you can

0:03:05.040,0:03:10.239
tag us we are at microbit uncore edu

0:03:10.239,0:03:14.319
that's microbit uncore edu on Twitter or

0:03:14.319,0:03:17.519
X that's a really good idea J it will be

0:03:17.519,0:03:19.720
lovely to see how different classes and

0:03:19.720,0:03:22.599
schools get on in their environments so

0:03:22.599,0:03:25.280
I think we're ready to get started Giles

0:03:25.280,0:03:26.640
can you think of anything else we need

0:03:26.640,0:03:29.360
to mention before we start coding I

0:03:29.360,0:03:31.799
think as we're making a species counter

0:03:31.799,0:03:33.319
I think it would be really good just to

0:03:33.319,0:03:35.319
make sure that everyone knows exactly

0:03:35.319,0:03:39.200
what a species is great call Giles okay

0:03:39.200,0:03:42.159
so a species is a set of animals or

0:03:42.159,0:03:45.040
plants who have similar characteristics

0:03:45.040,0:03:46.959
to each other so they all look similar

0:03:46.959,0:03:48.319
to each other and they have similar

0:03:48.319,0:03:50.680
characteristics so for

0:03:50.680,0:03:53.400
example let's look at these pictures

0:03:53.400,0:03:56.280
here so let me just remove this so that

0:03:56.280,0:04:00.239
you can see it better there we go so so

0:04:00.239,0:04:02.920
um in the in the slide here we've got

0:04:02.920,0:04:05.599
lots of different animals but how many

0:04:05.599,0:04:08.319
species have we got Giles oh that's a

0:04:08.319,0:04:09.920
really interesting question it's quite

0:04:09.920,0:04:11.720
tricky actually um I'm going to start

0:04:11.720,0:04:13.879
with the ones that all look the same so

0:04:13.879,0:04:17.199
I can see some snails there um some in

0:04:17.199,0:04:19.639
their shells some out of their shells so

0:04:19.639,0:04:21.759
I think the three pictures of snails

0:04:21.759,0:04:23.479
that's one

0:04:23.479,0:04:27.199
species um I can see Robin again a bird

0:04:27.199,0:04:28.800
and I don't see any other birds on there

0:04:28.800,0:04:31.160
so I think that's probably another

0:04:31.160,0:04:35.840
species um we've got oh two butterflies

0:04:35.840,0:04:38.960
so I think two butterflies uh probably

0:04:38.960,0:04:43.199
one more species and then I can see a

0:04:43.199,0:04:47.000
fly and I can see a worms so I think

0:04:47.000,0:04:49.759
have we got five species there blonded

0:04:49.759,0:04:53.360
well done yes I think that is spot on

0:04:53.360,0:04:54.840
and that means that everyone is very

0:04:54.840,0:04:56.759
clear and everyone can be super accurate

0:04:56.759,0:04:58.320
when they go out and they start logging

0:04:58.320,0:05:01.560
their species later thanks chares so

0:05:01.560,0:05:05.720
let's get coding um so the what we're

0:05:05.720,0:05:07.160
going to do is we're going to bring you

0:05:07.160,0:05:09.720
to the makecode editor

0:05:09.720,0:05:13.000
website so um you'll find that you can

0:05:13.000,0:05:15.320
see it on the banner now at make code.

0:05:15.320,0:05:18.080
microbit

0:05:29.720,0:05:31.520
you can get started with right away

0:05:31.520,0:05:34.520
without needing any logins or passwords

0:05:34.520,0:05:36.280
and so on so there is a sign-in button

0:05:36.280,0:05:37.800
on the top right so schools with

0:05:37.800,0:05:39.960
Microsoft or Google logins can use that

0:05:39.960,0:05:41.680
but we don't need to we can jump

0:05:41.680,0:05:44.160
straight in um now I've got some

0:05:44.160,0:05:46.199
projects showing here because I've used

0:05:46.199,0:05:48.039
it before if it's your first time you

0:05:48.039,0:05:50.440
might not have that but you will have

0:05:50.440,0:05:52.479
new project the new project button and

0:05:52.479,0:05:53.800
that's what we're going to jump straight

0:05:53.800,0:05:56.759
into also in the settings on make code

0:05:56.759,0:05:58.560
in the top right there's a little Cog

0:05:58.560,0:06:00.720
here next to the sign-in button that's

0:06:00.720,0:06:02.560
where you'll find different languages if

0:06:02.560,0:06:04.680
you want to change the language to to

0:06:04.680,0:06:09.400
your local language so click on new

0:06:09.400,0:06:11.680
project and the first thing it does is

0:06:11.680,0:06:14.120
asks me to give it a name so if you're

0:06:14.120,0:06:16.680
doing the same project as the CL it's a

0:06:16.680,0:06:19.120
really good idea to make sure that your

0:06:19.120,0:06:21.400
name or your student name is is is

0:06:21.400,0:06:24.360
included in the project name and today

0:06:24.360,0:06:28.000
we're making a biodiversity counter so

0:06:28.000,0:06:29.840
I'm going to name my project blana

0:06:29.840,0:06:33.800
biodiversity counter and click on

0:06:33.800,0:06:36.520
create okay so this has opened up the

0:06:36.520,0:06:39.800
make code editor so we can see that

0:06:39.800,0:06:41.759
there's some blocks of code already in

0:06:41.759,0:06:43.400
the workspace here on the right now I'm

0:06:43.400,0:06:45.120
going to make that a little bit bigger

0:06:45.120,0:06:47.120
by using this plus sign in the bottom

0:06:47.120,0:06:49.240
right hand side going to zoom in on my

0:06:49.240,0:06:51.800
blocks of code a little bit do you think

0:06:51.800,0:06:53.720
that's large enough Giles I think so I

0:06:53.720,0:06:55.000
can see that really clearly thank you

0:06:55.000,0:06:58.080
blet okay brilliant so um this is the

0:06:58.080,0:06:59.599
workspace this is where you can draw

0:06:59.599,0:07:01.639
drag blocks of codee around and you drag

0:07:01.639,0:07:03.680
them in from the toolbox over here and

0:07:03.680,0:07:06.199
you build your code in this space now we

0:07:06.199,0:07:08.160
won't need the forever block for our

0:07:08.160,0:07:09.560
project today so I'm actually going to

0:07:09.560,0:07:11.160
show you how to delete the blocks as

0:07:11.160,0:07:14.919
well by dragging them onto the uh the

0:07:14.919,0:07:17.080
the menu here or the toolbox and then

0:07:17.080,0:07:19.080
just letting go and it will delete a

0:07:19.080,0:07:22.400
block um when you have a look inside

0:07:22.400,0:07:24.120
this menu you can see that there's lots

0:07:24.120,0:07:27.080
of pre-prepared blocks of code ready to

0:07:27.080,0:07:29.720
go you don't need to have to know what

0:07:29.720,0:07:32.160
to type like you would in a text based

0:07:32.160,0:07:34.800
um editor you can just take the blocks

0:07:34.800,0:07:36.639
and you can drag and drop them onto the

0:07:36.639,0:07:38.520
workspace as you need

0:07:38.520,0:07:41.360
them um on the left hand side here we've

0:07:41.360,0:07:44.319
also got the simulator so we'll be using

0:07:44.319,0:07:46.240
this today to check that everything is

0:07:46.240,0:07:48.840
working before we put our code on our

0:07:48.840,0:07:51.919
microbit and take them outside to do our

0:07:51.919,0:07:55.720
biodiversity logging um we'll also be

0:07:55.720,0:07:58.360
using the download button we just take

0:07:58.360,0:08:00.039
off the banner for a second perfect

0:08:00.039,0:08:02.360
thank you Giles so the download button

0:08:02.360,0:08:04.120
here bottom left that will be used at

0:08:04.120,0:08:07.159
the end of the session so that we uh can

0:08:07.159,0:08:10.840
put our code onto our microbit so we

0:08:10.840,0:08:12.919
will if I just show you on my screen let

0:08:12.919,0:08:17.479
me get a view of me on the screen

0:08:17.560,0:08:20.840
second so on the microbit here we will

0:08:20.840,0:08:23.159
use the USB lead we will plug that into

0:08:23.159,0:08:25.000
our computer and we'll plug the other

0:08:25.000,0:08:26.960
end into our microbit and we will press

0:08:26.960,0:08:28.560
download and we will put the code on the

0:08:28.560,0:08:30.720
microbit and then attach the battery

0:08:30.720,0:08:32.560
pack so that we can bring it outside

0:08:32.560,0:08:36.320
into the environment and uh code and use

0:08:36.320,0:08:40.279
the code we have created that way okay

0:08:40.279,0:08:42.800
so coming back to our project that we're

0:08:42.800,0:08:45.839
going to create today um I'm going to

0:08:45.839,0:08:48.399
stop here and have a little think about

0:08:48.399,0:08:51.480
what my program is going to do I want to

0:08:51.480,0:08:54.560
use my microbit in the playground ler to

0:08:54.560,0:08:57.279
count two different things the number of

0:08:57.279,0:08:59.200
animal species and the number of plant

0:08:59.200,0:09:01.560
species species I want the microbit to

0:09:01.560,0:09:03.880
count for me and remember how many of

0:09:03.880,0:09:05.200
these species I spotted because there's

0:09:05.200,0:09:06.800
absolutely no way I'm going to keep all

0:09:06.800,0:09:09.680
that information in my head so I want

0:09:09.680,0:09:11.640
the microbit to remember the information

0:09:11.640,0:09:14.079
or the data so that means I need to

0:09:14.079,0:09:17.800
create two different variables so in the

0:09:17.800,0:09:21.160
toolbox here we've got variables as a

0:09:21.160,0:09:24.320
red menu section of the menu so if I

0:09:24.320,0:09:26.680
click on variables you'll see it gives

0:09:26.680,0:09:28.720
me one option right now and that is to

0:09:28.720,0:09:31.240
make a variable able so variables are

0:09:31.240,0:09:33.000
like containers they will hold different

0:09:33.000,0:09:34.680
pieces of information and they will keep

0:09:34.680,0:09:37.160
updating as we use the microbit and add

0:09:37.160,0:09:38.120
more

0:09:38.120,0:09:41.240
information so the two uh variables I

0:09:41.240,0:09:44.120
want to create today are I click on make

0:09:44.120,0:09:45.640
a variable and then I name them so I'm

0:09:45.640,0:09:48.200
going to call my first one animal

0:09:48.200,0:09:51.399
species and click okay and then I'm

0:09:51.399,0:09:53.519
going to oh you see straight away some

0:09:53.519,0:09:56.079
Co some blocks of code have appeared

0:09:56.079,0:09:57.519
because I've created this variable so

0:09:57.519,0:09:58.880
we've got some other blocks of code here

0:09:58.880,0:10:02.160
we can use later and then I click on

0:10:02.160,0:10:03.920
make a variable again and I'm going to

0:10:03.920,0:10:05.880
call this plant

0:10:05.880,0:10:09.880
species and click on okay so now I've

0:10:09.880,0:10:14.000
got options to use these blocks of code

0:10:14.000,0:10:17.640
to change it from animal to plant when I

0:10:17.640,0:10:20.320
need it and I've made my two variables

0:10:20.320,0:10:21.959
if I go back into variables here I can

0:10:21.959,0:10:23.800
see them sitting here animal species and

0:10:23.800,0:10:24.880
plant

0:10:24.880,0:10:28.000
species okay so let me just delete that

0:10:28.000,0:10:31.040
properly there we go

0:10:31.040,0:10:34.240
so everyone approaches coding a little

0:10:34.240,0:10:35.959
bit differently and sometimes there are

0:10:35.959,0:10:37.440
different ways to achieve the same

0:10:37.440,0:10:39.920
things so Giles what would you do next

0:10:39.920,0:10:41.880
now that we've created the variables

0:10:41.880,0:10:43.320
well I was just thinking about that when

0:10:43.320,0:10:45.800
I turn on my mic a bit and the program

0:10:45.800,0:10:49.320
starts I won't have counted any Vari I

0:10:49.320,0:10:51.200
won't have counted any animal species or

0:10:51.200,0:10:53.920
plant species yet so I'm thinking

0:10:53.920,0:10:56.760
whether it's a good idea to set both

0:10:56.760,0:11:00.240
variables to zero so what I might do is

0:11:00.240,0:11:03.320
I might go into the variables

0:11:03.320,0:11:07.560
menu and take set plant species to zero

0:11:07.560,0:11:11.079
and drag that into the on block anything

0:11:11.079,0:11:13.760
you put in the onstart block will um the

0:11:13.760,0:11:15.880
microbit will carry out that instruction

0:11:15.880,0:11:17.639
when the program starts running so it's

0:11:17.639,0:11:20.320
going to set the zero uh set the plant

0:11:20.320,0:11:22.480
species to zero at the start of the

0:11:22.480,0:11:25.959
program then I drag the same block again

0:11:25.959,0:11:29.040
so I go back into variables and drag out

0:11:29.040,0:11:31.360
set plant species to zero again but I'm

0:11:31.360,0:11:35.040
going to change maybe plant species to

0:11:35.040,0:11:36.120
animal

0:11:36.120,0:11:39.480
species so we have plant species and

0:11:39.480,0:11:41.720
animal species both set to zero at the

0:11:41.720,0:11:43.320
start of the program do you think that's

0:11:43.320,0:11:46.600
a good idea blet yes definitely I would

0:11:46.600,0:11:48.160
I would have done the same thing at this

0:11:48.160,0:11:50.000
point for sure to make sure that the

0:11:50.000,0:11:51.920
microbit knows to start counting from

0:11:51.920,0:11:54.519
zero for each of those variables there's

0:11:54.519,0:11:56.760
one other thing I do as well um there's

0:11:56.760,0:11:58.720
nothing on the screen of the microbit

0:11:58.720,0:12:00.680
when you turn on at the moment and I

0:12:00.680,0:12:02.639
think it would be useful to also show a

0:12:02.639,0:12:04.959
zero on the screen so I'm going to add

0:12:04.959,0:12:07.519
in that instruction I'm going to go into

0:12:07.519,0:12:10.600
the basic menu so the menus are all

0:12:10.600,0:12:13.279
colorcoded and blue blocks are from the

0:12:13.279,0:12:15.399
basic menu I'm going to take the first

0:12:15.399,0:12:17.720
one here show number and I'm going to

0:12:17.720,0:12:20.800
drag that in to the onart block here

0:12:20.800,0:12:23.000
it's already got the number zero in it

0:12:23.000,0:12:25.120
and now you can see the simulator has

0:12:25.120,0:12:27.720
updated and when my mic bit starts it

0:12:27.720,0:12:31.600
will show a zero on the screen as well

0:12:31.600,0:12:34.040
okay so let's have a quick recap to to

0:12:34.040,0:12:35.680
make sure that everyone is keeping up

0:12:35.680,0:12:37.560
when they're coding along in their

0:12:37.560,0:12:40.000
classrooms so have you made your

0:12:40.000,0:12:41.920
variables remember we went into

0:12:41.920,0:12:44.320
variables we clicked make a variable and

0:12:44.320,0:12:46.720
we made two one called animal species

0:12:46.720,0:12:50.120
and one called plant species okay have

0:12:50.120,0:12:52.800
you set your variables to zero we took

0:12:52.800,0:12:55.600
out this one set plant species to zero

0:12:55.600,0:12:56.959
and we used it

0:12:56.959,0:12:59.480
twice but we changed it using the drop

0:12:59.480,0:13:01.399
down menu from plant species to animal

0:13:01.399,0:13:04.920
species and we popped that into the

0:13:04.920,0:13:07.880
onstart block and then we added a zero

0:13:07.880,0:13:09.959
through using the show Number Block here

0:13:09.959,0:13:14.720
in the basic menu as well okay

0:13:14.720,0:13:16.639
so that

0:13:16.639,0:13:20.519
means we have got started but there's

0:13:20.519,0:13:23.440
two very important things that we need

0:13:23.440,0:13:25.920
to do next and they're both to do with

0:13:25.920,0:13:28.079
using the buttons on the microbit

0:13:28.079,0:13:29.480
because we're going to be using both

0:13:29.480,0:13:33.079
button a and button B uh that are on the

0:13:33.079,0:13:35.600
front of the microbit so we're going to

0:13:35.600,0:13:37.880
use one button to log data about animal

0:13:37.880,0:13:39.760
species and we're going to use another

0:13:39.760,0:13:41.680
button to log the data about plant

0:13:41.680,0:13:45.959
species so let's start with button a

0:13:45.959,0:13:48.079
here are a few

0:13:48.079,0:13:52.160
clues for what we're going to

0:13:52.160,0:13:54.880
use button a for any

0:13:54.880,0:13:59.880
ideas well um let me see we had uh a

0:13:59.880,0:14:03.040
butterfly we've had uh a bird and a

0:14:03.040,0:14:07.040
snail so I think a is going to be for

0:14:07.040,0:14:10.560
Animals correct yes A is for Animals is

0:14:10.560,0:14:13.360
animals that's easy to remember yes so

0:14:13.360,0:14:15.480
all the pictures are animals so button a

0:14:15.480,0:14:18.240
is going to lck the animal species so to

0:14:18.240,0:14:19.800
make something happen on the micob bit

0:14:19.800,0:14:22.240
when we press button a we will need the

0:14:22.240,0:14:24.680
on button a press block so you'll find

0:14:24.680,0:14:26.959
this in a new menu the the purple

0:14:26.959,0:14:29.839
purpley pink menu here called

0:14:29.839,0:14:32.600
if I go into that menu the very first

0:14:32.600,0:14:35.040
block is on button a press so let's pull

0:14:35.040,0:14:37.360
that out and put that into the

0:14:37.360,0:14:41.040
workspace okay so we want the animal

0:14:41.040,0:14:44.320
species uh variable to update by one

0:14:44.320,0:14:47.480
each time we press button a so that

0:14:47.480,0:14:49.000
means I need to go back into my

0:14:49.000,0:14:52.759
variables menu in here and I I'm looking

0:14:52.759,0:14:55.160
at the second block here I want to

0:14:55.160,0:14:57.639
change something by one when I press

0:14:57.639,0:15:00.920
button a now when I pull this out just

0:15:00.920,0:15:02.920
pop it there for a moment it it goes

0:15:02.920,0:15:04.240
this strange color because it's not

0:15:04.240,0:15:07.079
inside uh a working block at the moment

0:15:07.079,0:15:09.000
but I can still manipulate it here I can

0:15:09.000,0:15:10.720
still change it to what I want so I

0:15:10.720,0:15:12.600
actually want to change the animal

0:15:12.600,0:15:14.839
species on but a so I'm going to switch

0:15:14.839,0:15:17.759
that to animal species and I pop it

0:15:17.759,0:15:22.240
inside the on button a pressed block so

0:15:22.240,0:15:25.040
that means that the microbit will update

0:15:25.040,0:15:27.079
the total number of animal

0:15:27.079,0:15:31.720
species each time we press button a uh

0:15:31.720,0:15:34.720
on the micro bit

0:15:34.759,0:15:37.959
itself okay Planet I I got a question

0:15:37.959,0:15:40.000
here I I've been following along I've

0:15:40.000,0:15:41.880
got the same blocks as you but when I

0:15:41.880,0:15:45.560
press button a I just get zero on the

0:15:45.560,0:15:47.839
screen even though I keep pressing

0:15:47.839,0:15:50.639
button a have I done something wrong not

0:15:50.639,0:15:53.680
at all Giles um

0:15:53.680,0:15:56.560
I I have the same thing happening on my

0:15:56.560,0:16:00.440
mic bit on here so I might be pressing

0:16:00.440,0:16:02.519
on my simulator I might press butt a a

0:16:02.519,0:16:04.240
couple of times but my screen has not

0:16:04.240,0:16:06.639
changed so you have not done anything

0:16:06.639,0:16:09.839
wrong you just have not given the

0:16:09.839,0:16:12.120
microbit the instructions to do that

0:16:12.120,0:16:15.560
part yet okay the micr will only do what

0:16:15.560,0:16:18.160
you ask it to do if we want to see the

0:16:18.160,0:16:20.839
total on the LED display then we need to

0:16:20.839,0:16:22.360
put those instructions in and ask the

0:16:22.360,0:16:24.120
microbit to show it to us so let's add a

0:16:24.120,0:16:26.000
few more blocks to make that

0:16:26.000,0:16:30.880
happen so if we go into to um what are

0:16:30.880,0:16:32.440
we going to go we're going to go into

0:16:32.440,0:16:35.519
into basic first of all and we're going

0:16:35.519,0:16:39.399
to scroll down to the show icon block

0:16:39.399,0:16:42.319
okay so this will help us know that when

0:16:42.319,0:16:44.600
it shows us data on the LED display it's

0:16:44.600,0:16:48.839
talking about animal species data so I'm

0:16:48.839,0:16:51.440
going to pop that in here and I'm going

0:16:51.440,0:16:53.639
to change the icon from a heart to

0:16:53.639,0:16:55.480
something that resembles an animal

0:16:55.480,0:16:57.920
species so let's have a look got lots of

0:16:57.920,0:17:00.240
pre-prepared icons here right I'm going

0:17:00.240,0:17:02.680
to choose the duck so we've got a little

0:17:02.680,0:17:06.559
duck icon to to stand for our animal

0:17:06.559,0:17:09.640
species right um the next thing I'm

0:17:09.640,0:17:11.360
going to do is I'm going to go back into

0:17:11.360,0:17:13.280
basic and I'm going to take the show

0:17:13.280,0:17:15.439
number block again and I'm going to pop

0:17:15.439,0:17:18.400
it in below now this time I don't want

0:17:18.400,0:17:21.160
to the show Number Block to show us zero

0:17:21.160,0:17:23.199
I want it to show the total number of

0:17:23.199,0:17:25.880
animal species on the LED display so

0:17:25.880,0:17:29.039
I've got to go back into variables and

0:17:29.039,0:17:31.520
find my animal species block the small

0:17:31.520,0:17:34.440
one here so I take this out and you can

0:17:34.440,0:17:37.720
see how it can slot in over the zero and

0:17:37.720,0:17:41.280
replace it so we do that and then our

0:17:41.280,0:17:43.039
code will

0:17:43.039,0:17:46.520
update okay so now if we test if it's

0:17:46.520,0:17:48.679
working on the simulator it should work

0:17:48.679,0:17:51.000
this time but actually I've got an idea

0:17:51.000,0:17:53.880
to test that Giles so do you remember

0:17:53.880,0:17:57.000
this this slide that we looked at

0:17:57.000,0:18:01.320
earlier oh yeah was it again how many

0:18:01.320,0:18:03.559
times I press a if these were the

0:18:03.559,0:18:06.080
animals I'd seen outside oh gosh right

0:18:06.080,0:18:07.960
I'm trying to remember again we had

0:18:07.960,0:18:11.320
snails and uh that was one species and

0:18:11.320,0:18:12.919
then we had two butterflies but that's

0:18:12.919,0:18:14.520
only one more species because they're

0:18:14.520,0:18:17.000
both both the same species so that's one

0:18:17.000,0:18:21.240
more uh we had a bird and we've got a

0:18:21.240,0:18:23.440
fly and I've got a worm so I think it

0:18:23.440,0:18:26.159
was five different animal species that

0:18:26.159,0:18:29.840
we have there correct well done J yes so

0:18:29.840,0:18:33.159
on my simulator now I am going to press

0:18:33.159,0:18:35.400
a five times and let's see if we can see

0:18:35.400,0:18:38.039
something happening and

0:18:38.039,0:18:44.120
see yes there we go one two 3

0:18:44.120,0:18:47.039
4 five so we've now given the correct

0:18:47.039,0:18:49.080
instructions yeah so we can see now that

0:18:49.080,0:18:50.919
when we log one it will give us some

0:18:50.919,0:18:52.960
feedback on the LED display to know that

0:18:52.960,0:18:56.919
it's happened um so if everyone has got

0:18:56.919,0:19:00.799
this part coded then that means we are

0:19:00.799,0:19:04.360
halfway there

0:19:05.480,0:19:07.280
yay

0:19:07.280,0:19:10.360
fantastic fantastic so we're halfway

0:19:10.360,0:19:12.799
there um and we've told the microb bit

0:19:12.799,0:19:14.400
what to do when we press button a when

0:19:14.400,0:19:17.480
we're counting animal species but we

0:19:17.480,0:19:20.600
haven't yet told it what to do when we

0:19:20.600,0:19:24.320
press button B now I wonder if anyone

0:19:24.320,0:19:27.600
can remember what are we going to count

0:19:27.600,0:19:30.000
when we press but button B can anyone

0:19:30.000,0:19:31.760
remember that

0:19:31.760,0:19:36.360
I ah right so we've got uh some flowers

0:19:36.360,0:19:37.840
we've got a

0:19:37.840,0:19:43.640
tree um oh and some more plants oh is it

0:19:43.640,0:19:45.159
plant species

0:19:45.159,0:19:48.000
Jiles might be plant species that we're

0:19:48.000,0:19:49.640
getting when we press button

0:19:49.640,0:19:52.240
D so what we want to do is we want to

0:19:52.240,0:19:55.640
use button B to to log plant species so

0:19:55.640,0:19:59.840
what we can do now is we can dup at or

0:19:59.840,0:20:02.960
copy the blocks that we have for button

0:20:02.960,0:20:04.880
a I wonder bled could you show us how to

0:20:04.880,0:20:05.960
do

0:20:05.960,0:20:07.960
that what do you can you just tell us

0:20:07.960,0:20:09.640
what you're doing there to get that that

0:20:09.640,0:20:12.240
menu to pop up yeah so I've put my

0:20:12.240,0:20:15.360
cursor over the entire block on button a

0:20:15.360,0:20:17.520
pressed and then I've right clicked and

0:20:17.520,0:20:19.520
then I get the menu at duplicate at the

0:20:19.520,0:20:21.240
top so you can duplicate that's one way

0:20:21.240,0:20:22.919
of doing it or you can just fetch the

0:20:22.919,0:20:25.360
blocks again uh from the toolbox in the

0:20:25.360,0:20:27.000
middle but just because it's quicker and

0:20:27.000,0:20:28.840
easier we're going to show you uh how to

0:20:28.840,0:20:30.600
duplicate so if you click on that and

0:20:30.600,0:20:32.720
duplicate the block you'll see again

0:20:32.720,0:20:34.440
like a bit like it did before the blocks

0:20:34.440,0:20:36.559
have gone a funny color uh and that's

0:20:36.559,0:20:39.520
because we've got two on button a press

0:20:39.520,0:20:41.919
blocks and we can only have one uh set

0:20:41.919,0:20:43.960
of instructions for what to do when you

0:20:43.960,0:20:45.679
press button a otherwise the microbit

0:20:45.679,0:20:48.159
will get really confused so first thing

0:20:48.159,0:20:51.360
we need to do is to change button a to

0:20:51.360,0:20:55.919
button B okay and then because we're not

0:20:55.919,0:20:57.720
counting animal species anymore we need

0:20:57.720,0:21:01.159
to change animal species to plant

0:21:01.159,0:21:03.080
species and I think it would be a good

0:21:03.080,0:21:05.280
idea to show a different picture at this

0:21:05.280,0:21:07.480
point not a duck so we'll pick something

0:21:07.480,0:21:09.760
else so if you click on that have a look

0:21:09.760,0:21:11.760
and pick something there is I think

0:21:11.760,0:21:13.960
there's a fork icon that looks a little

0:21:13.960,0:21:17.279
bit like a tree that's it that one we

0:21:17.279,0:21:19.919
can pick that you can also draw your own

0:21:19.919,0:21:21.640
plant icon as well if you like you can

0:21:21.640,0:21:24.360
use the show LEDs Block in the basic

0:21:24.360,0:21:25.840
category and you can draw your own

0:21:25.840,0:21:27.880
picture of an animal or a plant but

0:21:27.880,0:21:29.480
we're just going to pick the the fork

0:21:29.480,0:21:32.039
icon because it looks a bit like a tree

0:21:32.039,0:21:33.799
uh and then I think there's one more

0:21:33.799,0:21:35.440
thing we need to change yeah well

0:21:35.440,0:21:37.240
spotted bled because at the moment the

0:21:37.240,0:21:39.159
code is going to show the animal species

0:21:39.159,0:21:40.720
number when we press button B and that

0:21:40.720,0:21:42.600
would be wrong so we need to click on

0:21:42.600,0:21:45.640
the little arrow on that and change that

0:21:45.640,0:21:48.120
to plant

0:21:48.120,0:21:49.640
species

0:21:49.640,0:21:52.039
perfect thank you Giles I think that's

0:21:52.039,0:21:53.520
looking like it should work really well

0:21:53.520,0:21:55.320
and we should be able to test out button

0:21:55.320,0:22:00.679
B on the simulator now as well um so if

0:22:00.679,0:22:04.159
I was outside and these were all the

0:22:04.159,0:22:06.159
plants I saw while I was in my

0:22:06.159,0:22:09.240
playground how many plant species would

0:22:09.240,0:22:12.120
I log how many times do I press button B

0:22:12.120,0:22:13.600
oh that's a good question because I can

0:22:13.600,0:22:15.400
see lots of flowers there so I might

0:22:15.400,0:22:18.200
want to keep clicking uh and click lots

0:22:18.200,0:22:19.799
of flowers but I need to think I need to

0:22:19.799,0:22:22.240
be really careful about this I think

0:22:22.240,0:22:24.480
there are only two species here because

0:22:24.480,0:22:26.960
I've got flowers like daisies they look

0:22:26.960,0:22:28.520
the same so although there's lots of FL

0:22:28.520,0:22:31.159
flowers there that's only one species

0:22:31.159,0:22:33.120
that I've spotted and then there's some

0:22:33.120,0:22:35.240
Ivy some leaves growing in the middle so

0:22:35.240,0:22:37.720
I think here if I saw that when I went

0:22:37.720,0:22:40.720
outside I would log two plant species I

0:22:40.720,0:22:44.279
would press button B twice fantastic

0:22:44.279,0:22:46.559
that is very accurate and correct so I'm

0:22:46.559,0:22:51.679
going to do button B twice now on my

0:22:51.679,0:22:54.000
simulator and there we go we can see the

0:22:54.000,0:22:56.240
plant icon came up and the number came

0:22:56.240,0:22:57.919
up each time as well which is exactly

0:22:57.919,0:23:00.919
what we've asked it to do using the code

0:23:00.919,0:23:03.360
so that's that's fantastic Planet that's

0:23:03.360,0:23:05.600
really good but the number just flashes

0:23:05.600,0:23:10.440
up what if I can't remember the number

0:23:10.440,0:23:13.240
of animal species and plant species is

0:23:13.240,0:23:15.559
there a way we can get to see the the

0:23:15.559,0:23:18.039
sort of running total without having to

0:23:18.039,0:23:20.720
add a new one each time yeah that's a

0:23:20.720,0:23:21.960
really good point because I can't

0:23:21.960,0:23:23.559
remember now even how many animal

0:23:23.559,0:23:25.120
species we'd already logged a few

0:23:25.120,0:23:28.159
minutes ago so we definitely need to to

0:23:28.159,0:23:30.039
to add that in because we don't want to

0:23:30.039,0:23:33.799
get our numbers muddled up so um let's

0:23:33.799,0:23:35.919
use the icons again to make it clear

0:23:35.919,0:23:37.919
which total is coming up on the LED

0:23:37.919,0:23:42.039
display but let's also um use a new

0:23:42.039,0:23:43.720
input so we've used button a and we've

0:23:43.720,0:23:46.600
used button B to do our actual logging

0:23:46.600,0:23:49.640
but now let's use the touch logo on the

0:23:49.640,0:23:51.679
front of the microbit as the input to

0:23:51.679,0:23:54.080
show us our totals so you'll find that

0:23:54.080,0:23:56.880
in the inputs menu and if you scroll

0:23:56.880,0:23:59.440
right down past where it says microbit

0:23:59.440,0:24:03.120
V2 right down here we get the on Logo

0:24:03.120,0:24:05.919
pressed block so if I pull that out now

0:24:05.919,0:24:10.600
I'm going to use this as my input now I

0:24:10.600,0:24:12.799
said we wanted to use the icons again so

0:24:12.799,0:24:14.279
that's the next time we're going next

0:24:14.279,0:24:15.279
thing we're going to do we're going to

0:24:15.279,0:24:17.840
go to basic we're going to drag out our

0:24:17.840,0:24:20.799
show icon pop it in here and I'm going

0:24:20.799,0:24:23.640
to change this one to the animal icon

0:24:23.640,0:24:24.919
we' selected

0:24:24.919,0:24:28.360
earlier and then I want to show my total

0:24:28.360,0:24:31.159
to Al number of animal species counted

0:24:31.159,0:24:34.240
so if I go back into basic take show

0:24:34.240,0:24:38.080
number pop it in and then I find my

0:24:38.080,0:24:40.240
variable my animal species variable in

0:24:40.240,0:24:43.320
the variables menu pull that out and

0:24:43.320,0:24:46.880
that goes on top so that means when you

0:24:46.880,0:24:49.600
press the logo the duck icon will will

0:24:49.600,0:24:51.760
come up and then the total number of

0:24:51.760,0:24:54.480
animal species now I also want to to see

0:24:54.480,0:24:55.919
the plant species but I don't want it

0:24:55.919,0:24:58.520
all to happen too quickly it needs to be

0:24:58.520,0:25:00.279
clear when we read it off the screen and

0:25:00.279,0:25:02.360
then when there's numbers that are

0:25:02.360,0:25:04.799
two-digit or even three-digit numbers

0:25:04.799,0:25:06.720
they will scroll so we need a little bit

0:25:06.720,0:25:09.159
of time for the microbit to do its thing

0:25:09.159,0:25:11.760
so we're going to leave a small pause so

0:25:11.760,0:25:15.480
if I go back into basic and scroll down

0:25:15.480,0:25:18.120
find the pause block I'm going to pop

0:25:18.120,0:25:21.520
that in and let's pause for two

0:25:21.520,0:25:24.080
seconds that shows up as 2,000

0:25:24.080,0:25:27.000
milliseconds on the Block and then I'm

0:25:27.000,0:25:28.799
going to go back into basic and another

0:25:28.799,0:25:30.720
time and I'm going to get the clear

0:25:30.720,0:25:33.200
screen block here so that clean the

0:25:33.200,0:25:35.840
screen goes completely clear before it

0:25:35.840,0:25:37.240
me any of the

0:25:37.240,0:25:41.720
plant species data so now I want to show

0:25:41.720,0:25:43.799
the plant species data actually I'll

0:25:43.799,0:25:45.760
just do one more pause before that so

0:25:45.760,0:25:47.679
I'm going to duplicate that block be

0:25:47.679,0:25:50.000
doubly sure that the screen clears and

0:25:50.000,0:25:54.120
has time to clear now back into basic

0:25:54.120,0:25:57.880
take your show icon change that to our

0:25:57.880,0:26:02.640
tree like icon here go back into basic

0:26:02.640,0:26:06.080
take another show number and this time

0:26:06.080,0:26:08.559
in the variables menu I choose plant

0:26:08.559,0:26:14.159
species and put it in there so hopefully

0:26:14.159,0:26:16.080
that will have given the microbit the

0:26:16.080,0:26:18.679
instructions needed for us to see the

0:26:18.679,0:26:22.559
totals on the screen when we want to to

0:26:22.559,0:26:24.919
recap how many we've counted of each so

0:26:24.919,0:26:26.679
shall we try out on the simulator now

0:26:26.679,0:26:28.559
Giles I think that sounds like a really

0:26:28.559,0:26:30.000
good idea right I'm going to put you to

0:26:30.000,0:26:32.559
the test I'm going to show you some

0:26:32.559,0:26:34.840
pictures and see if you can count along

0:26:34.840,0:26:36.880
and correctly count the species I'm

0:26:36.880,0:26:40.000
going to reset my microb bit first just

0:26:40.000,0:26:41.760
clear any of the data we've done so far

0:26:41.760,0:26:42.799
so you would do that on the real

0:26:42.799,0:26:44.120
microbit with the reset button on the

0:26:44.120,0:26:45.880
back but I've just pressed this uh

0:26:45.880,0:26:49.080
symbol here on the simulator okay test

0:26:49.080,0:26:51.720
me fantastic are you ready yes okay here

0:26:51.720,0:26:54.840
we go that's a tree so that's a plant

0:26:54.840,0:26:57.159
species so that's one plant species so

0:26:57.159,0:26:59.559
far oh that's another tree so hang on I

0:26:59.559,0:27:02.159
need to have pressed B once but not

0:27:02.159,0:27:04.520
again because they're the same species

0:27:04.520,0:27:08.080
well done okay let's try one more right

0:27:08.080,0:27:09.840
that's a different plant species so I'm

0:27:09.840,0:27:12.080
going to press B again that's the second

0:27:12.080,0:27:14.880
plant species I've

0:27:15.000,0:27:17.679
seen there's our lovely Robin that's a

0:27:17.679,0:27:21.159
animal species a bird

0:27:21.159,0:27:25.320
okay and I'll give you one more okay

0:27:25.320,0:27:26.799
fantastic that's

0:27:26.799,0:27:31.080
another animal species so let's see if I

0:27:31.080,0:27:34.840
go to my touch logo and I click this now

0:27:34.840,0:27:36.000
let's see what

0:27:36.000,0:27:38.039
happens animals

0:27:38.039,0:27:41.159
to should clear the screen there a

0:27:41.159,0:27:44.720
little pause there two fantastic

0:27:44.720,0:27:49.200
fantastic well done woohoo so that's it

0:27:49.200,0:27:51.640
if you have got this far with us you

0:27:51.640,0:27:54.679
have now coded your biodiversity code

0:27:54.679,0:27:57.240
along uh biodiversity counter I should

0:27:57.240,0:28:01.060
say that you can use outside in your

0:28:01.060,0:28:07.200
[Applause]

0:28:07.200,0:28:09.519
playground two lots of Applause and

0:28:09.519,0:28:11.519
cheering that's marvelous so once you

0:28:11.519,0:28:15.159
know the number of the current number of

0:28:15.159,0:28:17.440
animal and plant species you could

0:28:17.440,0:28:19.720
monitor whether this changes over time

0:28:19.720,0:28:21.039
because you could count them again in

0:28:21.039,0:28:23.679
the future um you might want to try some

0:28:23.679,0:28:25.640
things in your local environment to

0:28:25.640,0:28:27.880
improve biodiversity and see if you get

0:28:27.880,0:28:29.480
better better numbers next time if you

0:28:29.480,0:28:31.840
get a more diverse environment with

0:28:31.840,0:28:34.200
different more different kinds of

0:28:34.200,0:28:36.320
plants and there's lots of other things

0:28:36.320,0:28:37.840
you can do with that data that you go

0:28:37.840,0:28:40.519
outside and collect you could present it

0:28:40.519,0:28:43.120
in bar charts or other kinds of graphs

0:28:43.120,0:28:45.399
tally charts you could share your

0:28:45.399,0:28:47.159
findings with other classes in your

0:28:47.159,0:28:49.559
school or you could compare your

0:28:49.559,0:28:51.600
playground to other outdoor environments

0:28:51.600,0:28:55.919
such as Parks or maybe even another

0:28:55.919,0:28:58.919
school fabulous so thank you for those

0:28:58.919,0:29:01.640
ideas Giles they're really useful we we

0:29:01.640,0:29:03.640
have finished coding but there is one

0:29:03.640,0:29:06.320
more really important thing to do you

0:29:06.320,0:29:09.880
need to transfer the code to your real

0:29:09.880,0:29:11.880
life microbit so you can use it to count

0:29:11.880,0:29:14.360
biodiversity in your playground outside

0:29:14.360,0:29:16.559
or another outside area so what we're

0:29:16.559,0:29:19.320
going to do is we're going to um use the

0:29:19.320,0:29:23.600
USB cable to plug our mic bits into the

0:29:23.600,0:29:25.559
computer or laptop that you've been

0:29:25.559,0:29:28.120
using now if you've been using tablets

0:29:28.120,0:29:29.360
then obviously there's a different way

0:29:29.360,0:29:32.159
to transfer the code um I won't demo

0:29:32.159,0:29:34.960
that today but the link that is now

0:29:34.960,0:29:36.880
showing on screen will give you all the

0:29:36.880,0:29:38.919
different options for how to get code

0:29:38.919,0:29:41.200
onto your microbit tablets included so

0:29:41.200,0:29:43.039
you can have a look at that instead but

0:29:43.039,0:29:45.799
I'll just do a very quick demo of how to

0:29:45.799,0:29:48.440
get it on if you're using a laptop or a

0:29:48.440,0:29:52.080
tablet or a um sorry a desktop computer

0:29:52.080,0:29:56.240
so the small part of the USB cable goes

0:29:56.240,0:29:58.480
into the top of the microbit so you can

0:29:58.480,0:30:00.519
see there and then I'm going to plug

0:30:00.519,0:30:01.640
this

0:30:01.640,0:30:05.640
into my um my laptop that I'm using so

0:30:05.640,0:30:08.519
I'm plugging it in here the USB end of

0:30:08.519,0:30:12.159
it goes in okay now I'm just going to

0:30:12.159,0:30:16.240
share my screen before I

0:30:16.240,0:30:19.519
plug the rest of it in so one second

0:30:19.519,0:30:23.760
stop there I'm going to go

0:30:23.760,0:30:25.279
to

0:30:25.279,0:30:29.240
this okay now if I do this this way and

0:30:29.240,0:30:31.399
I get up my

0:30:31.399,0:30:34.200
downloads you will see something appear

0:30:34.200,0:30:36.200
in this menu on the left when I plug in

0:30:36.200,0:30:37.080
my

0:30:37.080,0:30:39.559
microbit so I've plugged it

0:30:39.559,0:30:43.640
in keep an eye here Tada the microbit

0:30:43.640,0:30:45.840
drive has appeared there because my mic

0:30:45.840,0:30:47.960
bit has been plugged in so I know that

0:30:47.960,0:30:51.039
it's connected and so now that I've

0:30:51.039,0:30:54.559
plugged it in on my make code editor I

0:30:54.559,0:30:56.360
need to click on the download button and

0:30:56.360,0:30:58.600
follow the instructions on screen

0:30:58.600,0:31:01.960
so I click that now download and it's

0:31:01.960,0:31:03.519
downloading to my micro bit now if it's

0:31:03.519,0:31:05.279
the first time you've downloaded it may

0:31:05.279,0:31:07.440
ask you to pair it first but you simply

0:31:07.440,0:31:09.480
follow the instructions on screen and it

0:31:09.480,0:31:11.360
will then give you the option to

0:31:11.360,0:31:13.760
download it if that doesn't work for any

0:31:13.760,0:31:16.279
reason there's also a drag and drop

0:31:16.279,0:31:18.760
method where if you download the hex

0:31:18.760,0:31:21.720
file using the three dots next to the

0:31:21.720,0:31:23.760
download button you can click on

0:31:23.760,0:31:25.159
download as

0:31:25.159,0:31:29.679
file okay that has now gone to my

0:31:29.679,0:31:31.679
downloads you can see it here there's

0:31:31.679,0:31:34.120
our project that we just made and I can

0:31:34.120,0:31:36.480
now drag and drop that on top of my

0:31:36.480,0:31:39.559
microbit drive and my microbit will

0:31:39.559,0:31:41.200
start flashing on the back so I know

0:31:41.200,0:31:42.639
that that's working as well so that's

0:31:42.639,0:31:45.799
another way to get it on okay so once

0:31:45.799,0:31:47.919
you've got it on there of course the

0:31:47.919,0:31:49.840
next thing to do is to plug your battery

0:31:49.840,0:31:53.919
pack in unplug it from your uh computer

0:31:53.919,0:31:56.919
and then you can take it outside and get

0:31:56.919,0:31:59.760
going with love the diversity all around

0:31:59.760,0:32:02.559
