What We're Doing
We have caused one LED to blink, now it's time to up the stakes. Lets connect eight. We'll also have an opportunity to stretch the Metro a bit by creating various lighting sequences. 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
