Arduino RGB LED Matrix Prototype

21 December 2008 One Comment

My latest tinkering: An Arduino throwing data at a couple of shift registers that in turn power an 8×8 RGB LED matrix. I’ve only hooked up half of blue and red right now to get the multiplexing/programming right. Never done this before and it’s rather confusing. Right now it’s working with red, blue and Purple. I’m limited to 6+1 colors, not sure how to get more since I don’t think I can do pulse width modulation through a shift register. It’s fun so far.
