USB, LED, and resistor help? - 07/09/07 03:58 AM
Ok, so this would be so much simpler if I had a 588-pin port on the back of my computer, lol, but I want to use USB instead.
What I'm trying to do is create a grid of LEDs, 28 wide by 21 tall, and I want to be able to write a program (which I can do no problem once I figure the wiring out) to control each LED. I want to set it up so every LED has it's own I/O, and again, I want to power the LEDs and control them through USB.
My plan is to start off with a simple equalizer to hang on my wall (the end result will be a 6x8 panel that will hang on the wall, I'll post pictures when it's done!) and eventually write a program that will allow the beast to basically double as a second, single hue, super low resolution monitor so I can write some cool visualization programs for it.
Right, so I don't even really know how to go about wiring this up, especially not once I start thinking about resistors and stuff (which I super hope I don't need).
