CIRC02: 8 LED Fun

What We're Doing

This circuit is also a nice setup to experiment with writing your own programs and getting a feel for how the Metro works.

Along with controlling the LEDs we start looking into a few simple programming methods to keep your programs small: for() loops and array[]'s
