Hi all, I am wondering if you can help. I want to get an LED maxtrix to produce maximum light in the most efficient way, by having different (individual or rows of) LEDs illuminating at different intensities. So basically for a desired input of required light, I would like to achieve a minimum current draw from the the matrix.
I have looked at multiplexers and driving the matrix from my Arduino board, but i'm a bit lost. Can anyone point me a few directions?
