“Easy to program with Arduino IDE. Extremely small, and versatile.
I have it hooked up via SPI to a 0.96in colour screen, and a speaker from a singing birthday candle.
Orientation is also easy to read, which means you can use movement in place of switches.
And the onboard multi-color led can do R, G, B, C, M, Y, W which helps to communicate status quickly.
