Laser Harp

Weekly Log

Overview

Although instruments have come a long way from their origins, they still have room to grow. Inspired by the transition from acoustic to electronic instruments, the laser harp strives to introduce a new way of experiencing music. With the laser harp, one would be able to enjoy musical scales by touching rays of light. Since the harp will have different keys and scales, it is important that the system's programming is properly carried out so the user can easily operate the instrument. Moreover, the sensors must be properly installed and synced with the disturbance of the lasers' trajectories for the project to be successful.

Objectives

Learn how to use Arduino and MIDI.
Build a circuit connecting the laser diodes to the Arduino.
Determine which notes or sounds are feasible based on options available on MIDI.
Create code or adapt code from the reference source to work the Arduino microcontroller.
Build a frame for the harp through woodworking or 3D printing and assemble the parts.
