It detects a beat in a line level audio signal.

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

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

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

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.

It repeats your voice.

A theremin made out of two ultrasonic sensors.

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

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

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

Type Morse code on Arduino and display it on your computer's monitor.

This project started from FabLab of Boilchon High School. Turning the button changes the sound.

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

Combining multiple tones and create harmonic melody.
