Using an ATMega328 (Arduino Microcontroller), Chris Woodall writes: βI just finished my writeup for my Music Synthesizer kit project. The kit was made for a soldering workshop for the Boston University Artemis Project, which is a Women In Technology Summer Program for rising high school freshmen. I work for the BU EDF which normally makes electronics for physics experiments, but we also do outreach electronics programs.
Normally the workshop would have contained a POV light toy, but we wanted a change of pace and I took lead to develop a music synthesizer with an 8 button keyboard, which can also act as a sequencer. There is a phototransistor which can pick up a light based message generated by this page, which my coworker Sam Damask made to program in sequences and new waveforms.β
The design files and firmware can be found on the project GitHub page.
