Making LEDs flicker? Answered
I'm building a costume piece and I really want to have a gem flicker different colors, using LED backlighting. I know I've seen products that make the LEDs "chase" or "run" but, I want these four lights to go in a circular motion, so that the gem looks like it just has light flickering different colors inside or behind it. Can anyone tell me how to make that work or is it impossible?
