More on RGB LEDs

I was thinking about controlling multiple color LEDs to make an elaborate panel with different light areas that can be contolled remotely from a laptop. As each LED needs three PWM outputs and many microcontrollers have just a few of them (I mean PWM outputs) the use of a microcontroller per LED makes sense. It did for this project.

I've just changed the LED type for a Superflux RGB LED to get what you can see in the video. The next step is to make a version that can be addressed (also available from the same site) so as each LED can be commanded to show a certain color. (One PIC 12F675 plus a Superflux LED cost less than $2!).

I'll be using an Arduino board with an XBee wireless module to control a bunch of leds. Alternatively I could use a Wi-port to control the panel via wifi.
