Noise box synth lays down some beats

[Tim] sent us his Noise Box Synth. The box is a sixteen step synthesizer that can generate sine, square, triangle, and sawtooth waves as well as a collection of sound effects (video after the break). The hardware is simple; an Arduino, four potentiometers, four buttons, a switch, a speaker, and some LEDs. This was a gift for a three-year-old but we’d be just as happy unwrapping it ourselves. We didn’t find a schematic but all of the connections and hardware can be extrapolated from the source code.
Arduino sometimes gets a bad name around here. This project, [Tim's] first that uses Arduino, proves that the accessibility of the platform makes it possible to jump directly into the deep end. Catch the video after the break.








That’s…interesting. For the non-musically inclined would someone mind explaining what the purpose of this device is? It seemed to just make rhythmic beeps and boops then at the end it sounded like the sound FX from Microsoft pinball that ships with windows. What is the purpose?
