Inspiration

I have always been fascinated by lasers, as well as musical instruments. I thought I would create the best of both worlds in a manner that demonstrates EE knowledge, as well as one that I can leverage in music production.

What it does

Laser Beams are fired at photoresists at the top. When the beam is interrupted, the code plays the according note.

How I built it

Lots of soldering by hand, inputs to breadboard, heat shrink tubing,

Challenges I ran into

Trying to get the photoresistors to read as digital inputs, instead of analog inputs.

Accomplishments that I'm proud of

All the soldering, assembly, and electrical wiring

What I learned

While this was very challenging, I gained experience in electrical engineering, refined my abilities in Arduino coding, and sharpened my creative problem skills in order to complete this project

What's next for Arduino Laser Harp

I have ordered an Arduino IoT module. My next step is to have the laser be a "remote" for home IoT devices connected via Alexa. Functions and particular IoT devices (like light bulbs) can be turned on and off with a "strum" of the harp. I hope to incorporate many features into this based on the chord progressions that are played.
