Networked AVR.based RGB-led controllers?
I was thinking about making networked rgb-led controllers. What I was originally thinking was using a small avr (tiny11/12/13 or something like that) to control 1-3 leds (when multiple, in parallel, same color on all). Creating more of these and networking them with some sort of simple network. RS-232 or something. And then control them all from a PC.
If you don't understand what I'm talking about, imagine christmaslights, where each light can be any RGB color, individually controllable, from a computer.
Any hints or tips?
