Butt Light

The Butt Light (yeah I know, corny), is about the most elementary piece of hardware to introduce yourself, your kids and everyone else to the wonderful world of micro-controllers. The entire project has no input and only one output: an RGB LED. The few parts are all glued on a button cell clip. You can make surprisingly creative little gems with this ultra-simple device. Flashing, fading, dices, memory games. You can slowly move from extremely simple scripts to more complex firmware.”
