The laser harp project is now officially started. Building off of the circular buffer/ serial port example I got running last week, here is a demonstration of the system running with a single sensor:
A quick description of the project:
The laser harp is an electronic harp-like instrument that is played by breaking beams of laser light, which are arranged vertically. A microcontroller monitors each beam on the other side of the instrument by measuring a light sensor (currently a photoresistor), interprets the results and sends a corresponding MIDI message to the computer, which turns this into actual sound to play back.
A snapshot of the current software for the project is public domain and available from my website:
You will need the C18 compiler for the PIC 18F to compile without modification.
As the design starts to mature, I will document the schematics and include them as well. Cheers!
