Tim sent us a link to his Arduino noise box synth that he built. It has 16 programmable sequences, 4 waveforms, a noise generator and a random feature. Check out the link for a lot more information, including the source code.
This project is an Arduino based step sequencer, synthesizer and sound effects box. It was constructed a year ago as a third birthday present, and has recently come back to me for some ‘refurbishment’ – fresh batteries and some glue to fix LEDs that have been pushed into the box.
