paint can
this parts list should be sufficient for building the bluetooth 'paint can' color selector. (minus some resistors and wiring.)
it includes an encoder for selecting the color. this encoder has a built-in RGB LED, so it is a basic color-display mechanism by itself.
the power supply should deliver enough voltage to power another 30 or so LEDs. we have a strip of WS2801 displays left over from the last5 project, which I will try to use, but not sure if they still work.
if more illumunation is needed i'd add this ring of 24 LEDs, also using a WS2801 driver: https://www.sparkfun.com/products/12665
also threw in a tiny bluetooth USB dongle.
the final circuit should remain useful for any other general bluetooth mockups as well.
