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

It detects a beat in a line level audio signal.

An Arduino-based robot drummer. It works with a transistor noise-generator and an arrangement of servos hitting a can and a pair of piezos.

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

A theremin made out of two ultrasonic sensors.

Build a real, playable theremin music instrument. The theremin is played using two antennas without physical contact.

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.

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

This trick teaches you how to use Micro SD/SD card for Arduino and speaker.

This lesson aims to show how to interface an electret microphone with the analog input.

In this project, you're going to learn how you can play your own melody with a Piezo speaker, using code generated by Circuito.io

A simple Arduino Morse code machine with a button, LED, and a buzzer that translates your input into English while you are typing.

A simple talking clock using Arduino Uno and Talkie Library

This is an arduino based theremin which uses two ultrasonic sensors to control the volume and frequency of the sound output.

Chiming clock using RTC that has switchable chimes, cuckoo sounds, etc. and can also highlight special events.

It repeats your voice.

An octave of bananas makes a piano!

Use an Arduino to add digital effects on-board your guitar!

My first IoT project. Uses the Spark Core, Arduino Uno, and dynamic web content that come together creating a fun, educational music device.

This editor can be used for all DART based controllers. the layout, wich represents the real machine, can be personalized and saved

This 13 key Pushbutton Piano will play in any octave from C2-C7 (i.e. C2-C3, F#5-F#6, etc.) and uses a binary count to change semitones.

Arduino playing the Waldir Azevedo's musical theme "Brasileirinho" with the tone function and with a speaker.

Create your own DAB+ radio with an Arduino UNO, a 2x16 LCD, and 5 switches.

Library & sketches to control the TEA5767 FM radio module, using Arduino and an I2C LCD display. Release 02.00.00 is an arduino library.
