For use in DIY homebrew radio equipment such superheterodyne receivers, SDR, HAM QRP transceivers or RF generator.

Coffin dance aka Astronomia melody

Build an FM radio with alarm clock.

This is a musical Tesla Coil driven by an Arduino and Slayer-Exciter. Using an Arduino, you can play music with pure electricity!

This project is for making a 32-band audio (music) frequency spectrum analyzer / visualizer using Arduino.

The device that creates beautiful arpeggiated sequences according to the musical theory.

DIY AM/FM/SW/ DSP radio receiver, using Arduino Uno/Nano and a color display TFT ST7735 1.8in.

A small noise/drone synth with percussion mode. Made using the Mozzi library and two Arduino Nanos.

Arduino TEA5767 radio with analog meters for showing frequency and signal strength.

My project is a piano of four sounds that uses things that we find at home, bananas.

Listen to your inner body energy and vibrations. Project describes how to make electronic instrument that converts hand waves into music.

Turn an old organ console into a MIDI controller to use with desktop organ software like Hauptwerk or Grandorgue.

An easier way to train and deploy Tensorflow Lite RNN model on Arduino Nano 33 BLE Sense - for micro speech recognition.

Piezos used as contact microphones to activate LEDs and shine lights through Samba drums.

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

This Arduino project displays the approximate frequency of the loudest sound detected by a sound detection module.

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

Inspired by the popular meme, this project plays "Never Gonna Give You Up" by Rick Astley.

An easy to build and use stereo RDS FM receiver with RDA5807.

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

I designed and built a DIY Bluetooth Speaker with an integrated LED matrix. The LED matrix includes a number of different visualizations.

Making music with a keypad? Seems like a weird idea! But we will see with the good software, we can even make an electric guitar out of it!

A simple FM radio with a display that shows the frequency and audio amplifier.

This project presents program to detect musical notes and chords using Arduino (nano or above).
