The Laser Harp is a manipulation of the concept of a musical instrument. Instead of strings running from one side of a harp to another, I have created an instrument that uses red lasers to transgress the space where strings would usually be. When an object interrupts a laser, a photo-resistor responds, sending a voltage change to an Arduino microchip, which outputs the data to a laptop computer via USB. Drake Wilson then wrote a program that modulates a sound sample differently according to what laser was interrupted, and outputs the sound through the speakers. Essentially, the 16 lasers will create a 2 octave musical harp played by interrupting lasers. At the time of the presentation, only the first 8 “strings” are functional. As I complete the project there will be updates to my website.
