An LPD6803 based LED module is an “intelligent” pixel, it can memorize its color and passthrough the data and power connection. This means you can drive a lot (several thousand) intelligent pixels with just 4 cables (2x power and 2x data).
Take a look at ladyada’s very informative post about the LPD6803 module.
So where to buy these Intelligent, LPD6803 based Pixels? At my PixelInvaders Shop for example!
- An Arduino Compatible Board
- A 12V Power supply (an old ATX Power supply is perfectly fine)
- A strand of some LPD6803 based LED modules
- Some cables to connect the LPD6803 module
I had some cardboard angle laying around an thought, why not build a DIY Wall Washer.
And here is the result:
The wiring is very easy, take a look at this wiring diagram done by ladyada:
Connect pin 2 (yellow) to the green color of the LPD6803 Module.
Connect pin 3 (green) to the blue color of the LPD6803 Module.
Red is V+, Black is GND.
