Arduino Mini BMO

A working BMO robot complete with Arduino, accelerometer, distance sensor, buttons, and audio playback. I have been working on personality right now but you could of course add music playback and games too.

If the buttons are a little tight or loose depending on your printer simply scale the parts a little before slicing.
