A step motor itself can generate sound when it is controlled at at proper speeds. Let's see two motors play the "Marble Machine" song.

A stereo VU meter built with an Arduino Nano and two NeoPixel LED rings.

An electronic keyboard with 7 piano keys, programmed to Middle B/A/G/F/E/D/C, and an 8th button used to access a menu of preset songs.

This project uses an Arduino, a drawn keyboard using lead pencil, a paper, and a speaker.

For a digital Christmas, let your Arduino play songs with a piezo buzzer.

Choose a song with your remote and Arduino will play it. On the monitor will appear the musical note played.

Controls a few LEDs using an Arduino and Speech Recognition.

Simple FM radio based on RDA5807M module and Arduino Pro Mini 3.3V.

It detects a beat in a line level audio signal.

An update of the older version of the keyboard. Now it doesn't require switches on your breadboard, you can use your pc keyboard.

As a musician and music passionate, this little Keyboard is my first (but not last) Arduino project. Hope you have fun with it :)

We're showing how to use KY-038 Sound Sensor using Arduino. You can control LED by clap with the help of Arduino and sound sensor.

Translation of Morse code to text.

Implements speech recognition and synthesis using an Arduino DUE.

I wasn't happy with the way the square waves sound, so I explored using other methods of generating sound waves with Arduino.

This project shows how to control MP3 player via webpage using Arduino Uno.

Discover how to make an I2S Theremin based on the new Arduino I2S library.

Whats cooler than flashing LEDs? Flashing LEDs to a song with (drum roll please).... a tone!
