Topic: Control a 8x8 RGB LED Matrix (Read 3057 times) previous topic - next topic

I want to control my 8x8 RGB Matrix so I can turn on/off specific LEDs and change their color. My Matrix has 16 Pins on each site, so total 32. I've got an Arduino Uno + a Colors Shield. The plasma-example works great, and I know how to fill the Matrix. Can someone please give me an example like displaying "HELLO" (each letter separately?), and changing the color? It would also be great if you guys could show me how I can get this to work: http://arduino.cc/playground/Main/DirectDriveLEDMatrix (Life + Hello)

Thanks a lot!

This is for a single-color LED matrix. It's not going to work for the RGB 8x8, which is equivalent to 3 matrices of 8x8 LEDs, since you don't have that many pins available.
You need to use a different method, for example the one based on shift registers (74HC595). Plenty of examples out there (if you google).

I've got one Shift Register at home but I think it's really complicated to do it that way... Couldn't I control it with a Colorduino? It got enough pins for the RGB Matrix, but I need the code to control each LED separately..

Thanks
