In my orginization class last year I had to comunicate over the serial port to a bread board I made and light up some led's(one standard number led) it even had 2-way comunication through switches on the board
I probably still have the code somewhere and if you can do simple boolean algebra you can handle the ciruitry easily, actualy you could just send over binary and whire it directly to the led's if you just wanted three colors, otherwise you'll have to do some evaluations to get the intenisty and such wich will require about an hour of chip design

I don't bother with either, Nedit gets the job done just fine thank you. Since when do I need a text editor that can play tetris?
