Stereo Audio with an Arduino

Recently I’ve been posting a lot of projects that use an 8 bit resistor ladder digital to analog converter(DAC) and an Arduino to make sound.  (see the Arduino vocal effects box, the Arduino drum sampler, and my audio output tutorial).  The technique I’ve been using to make these DACs is very simple, it requires only a handful of 10k and …

Arduino Matrix sound machine

Matrix sound machine: Generative music with a particle system using Arduino

This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here. Creating emergent patterns that can be converted into sounds fascinates me. So this is my first experiment in building an arduino platform for creating such patterns. This version uses a Gameduino as its …
