Led Christmas Lights Answered

I have an idea but have no idea if it would even work. I would like to make a led string that can be two different colors. The idea is that I put the lights up in October and they are purple and orange for Halloween and then as Christmas approaches I can change them to green and white. That way I can put lights up one time and do it when it is still warm out and my neighbors wont think I'm nuts. I know I can weave two lines together and just switch plugs but that isn't complicated enough. I like to do things that are way more complicated than it needs to be but are really cool when they are done. my wife loves it.

Okay, make a string of RGB LEDs, wired in series (just to reduce the number of separate wires you need) to an Arduino, PicAxe, or Basic Stamp microcontroller connected to a triplet of PWM power supplies. Write two versions of the driver, one to configure the PWMs to produce orange and purple output, and the other to do green/red or green/white. Include a USB interface on the board, and connected to your always-on home server. When the date changes to 1 November, the computer should automatically change configurations for you.

'Nuff said. Spoken like a true Maker!
