Arduino laserharp circuit
Circuit for an Arduino based laserharp made from four resistors, three phototransistors and a speaker. Laser light passes through a diffraction grating at the bottom where it then splits and strikes three different phototransistors. To play a note, one of these beams of light needs to be interrupted.
