Along with coldclimate and his wiimote controlled rgb led , I am looking at ways of playing with RGB leds. Having found some damn cheap ones from rapid electronics, I am playing with the separate control of the mix of red, green and blue colors. It would be easy to get some blinkMs, and they are damn cool. I need to use three output pins for each led, and the PWM at that, blinkM’s use one pin , and that’s any one.

So what’s the point? Learning about what tricks can be used to control multiple LEDs , by using multiplexers etc. It’s a learning thing. Its just the start, obvously. To construct the things I want to make, I need to learn a fair bit about electronics. This is the fun bit.
