This is the binary bracelets lesson. We are going to code our initials on a bracelet we
can wear and show all our friends! Binary is a way of representing information using
only two options. Sometimes people think of this as only 1s and 0s. But you can represent
binary with combinations of on or off, up and down, in and out or really any set of
opposites. Hi, I'm Orion and I program robots here at PlayI. All computer and robot brains
at their most fundamental level are little electronic gates. When the gate is open, electricity
can flow through and when it's closed, electricity can't. An example of binary on the robot is
the robot's eyes. The robot's eyes are LEDs and those are lights that are either on or
off. It's a binary system, one or the other. We can use the lights to represent binary
numbers. If we have a set of robots, we can say that the first robot is the 1s place and
the second robot is the 2s place, the third robot is the 4s place and so on. That's how
you represent a binary number. The robots will do it with their binary eyes and count it out for you.
