Source code release for Electro-Music Festival 2015.
.zip file includes .ino files for:
As well as experimental code:
Monosynth with Arpeggiator (uses Sharp analog distance sensor)
The Electronic Bobbie (uses Parallax WS2812B multicolor LED)
These are all compatible with the Arduino IDE 1.0.5 (but not later versions). Don't forget to disconnect the MIDI hardware from digitial pins 0 and 1 when uploading, otherwise it won't work!
