Hi. I'm making a stained-glass peice for a friend and I'd like to have around 500 LED lights set behind it, controlled to light / dim / off in predefined sequences with a standalone PIC control board, powered by a 5V supply. I have a BS in computer engineering, but it's been a while since I did any hands-on electronics projects... Programming the PIC is not an issue, I know how to do that part.
I'm looking for a driver board (or just a component) with transistors that I could drive with the PIC to supply power to the lights. As I said, it needs to be standalone, so my buddy can just turn on the power and use a simple switch to choose between maybe 3 display patterns. I probably only really need 8 "channels", dimming would be a great feature. Is there an IC just filled with FETs that would handle powering say 80 LEDs on each pin? Could anyone recommend a schematic with minimal components? Suggestions would be greatly appreciated~
