Instead of using a keypad to open your front door or even your safe, why not control the mechanism by a slider that glides through pitches?

In this project, we replaced the strings of an old guitar with lasers and DIY beam splitters.

Play MIDI arpeggios in every scale and pattern. Record and loop your sequences. Modify your sequences even after recording and be creative.

Create your own music with OscPocketO, a synth and a drum machine, that can be synchronized!

Minimalistic USB MIDI gadget developed with Arduino UNO, TFT display and encoder to explore auto-generative music and dynamic patterns.

Play a custom tune when your treasure box is opened to warn you someone may be trying to thieve your stuff!

Using Arduino Uno a speaker and bunch of leds & jumper wires you can create a nice birthday gift.

This code/sketch displays the approximate frequency as well as the musical note played on an electronic keyboard or piano app.

Coffin dance aka Astronomia melody

VOLCADE is a MIDI controller for volca built with 7 arcade control board that switches between chord progressions using the arcade joystick.

What can you do in quarantine when all you have is an old Arduino Uno and some knobs? Check out the simple - but still fun - drum machine.

This project uses an ultrasonic sensor to allow a "hand wave" (no touch!) to trigger a series of LED's and the Happy Birthday song twice

A slide whistle that plays anything you program in, so you are not at risk of spreading or receiving germs.
