Description

I built a laser piano using LDRs and laser light diodes. I used an Arduino Leonardo Pro Micro connected to a speaker to generate sound.

There are five steps to make this project :
First Step: Marking, Cutting and Gluing base
Second Step: Inserting and attaching LDR and Laser diode in the cardboard
Third Step: Soldering
Making the Circuit
Coding

I have given rest of the details in the log.

Details

I built a laser piano using LDRs and laser light diodes. I used an Arduino Leonardo Pro Micro connected to a speaker to generate sound. You can modify the tune of the piano by tweaking in the code and changing the frequency. I wanted to create something cool which can produce music and I ended up making this.

Instructions and code are given in the step. Enjoy.
