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.
