1 00:00:04,279 --> 00:00:10,200 This is the binary bracelets lesson. We are going to code our initials on a bracelet we 2 00:00:10,200 --> 00:00:27,110 can wear and show all our friends! Binary is a way of representing information using 3 00:00:27,110 --> 00:00:35,420 only two options. Sometimes people think of this as only 1s and 0s. But you can represent 4 00:00:35,420 --> 00:00:44,999 binary with combinations of on or off, up and down, in and out or really any set of 5 00:00:44,999 --> 00:00:51,519 opposites. Hi, I'm Orion and I program robots here at PlayI. All computer and robot brains 6 00:00:51,519 --> 00:00:57,479 at their most fundamental level are little electronic gates. When the gate is open, electricity 7 00:00:57,479 --> 00:01:03,399 can flow through and when it's closed, electricity can't. An example of binary on the robot is 8 00:01:03,399 --> 00:01:08,649 the robot's eyes. The robot's eyes are LEDs and those are lights that are either on or 9 00:01:08,649 --> 00:01:14,270 off. It's a binary system, one or the other. We can use the lights to represent binary 10 00:01:14,270 --> 00:01:21,820 numbers. If we have a set of robots, we can say that the first robot is the 1s place and 11 00:01:21,820 --> 00:01:27,070 the second robot is the 2s place, the third robot is the 4s place and so on. That's how 12 00:01:27,070 --> 00:01:30,659 you represent a binary number. The robots will do it with their binary eyes and count it out for you.
