LightScroll

This is a light scroll thingy I wrote for the Beaglebone Black.

When you start it, it asks you about how much LEDs you have connected (which I should rewrite, because its the GPIO pin that the program ends on) and the GPIO pin that the first LED is on. Then it turns on the LEDs between those two pins in order, then turns them off in order, etc. until you press a button to stop it.

As you can see, the code sucks. I really hate that list of globals I have and really want to fix that. I already have noticed I have some unnecessary lines and operations, and I think there are some more.
