Arduino + old LED sign = Newness

TJ continues to make progress in converting an older 12' long (7 pixels high) green LED signboard to run from an Ardunio (Atmel 328) instead of it's original controller. With the new controller the sign will act as a frame buffer off of a host computer, allowing it to act as a spectrum analyzer and other neat effects not possible with most LED signboards.
