Simple, easy to build 2 x 14 bars stereo VU meter for representing audio level.

You’ll learn how to use the KY-037 sound detection sensor with Arduino. You can measure changes in the intensity of sound in an environment.

The Arduino clock that says it as it sees it.

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.

It detects a beat in a line level audio signal.

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

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.

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.

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 :)

Translation of Morse code to text.

From Siri to Amazon's Alexa, we're slowly coming to terms with talking to machines. Build your own voice command device with this tutorial.

Easy and intuitive serial MP3 player. How to use this inexpensive device with your Arduino?

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

Playing polyphony Happy birthday theme on Arduino Nano with three buzzers on a single mini breadboard.

This is an easy how-to make a mini-piano using Arduino, including a preset song!

If there was an Avengers game for Atari 2600, the soundtrack would sound like this...

A 16-step sequencer for bass, lead and drum sounds. Use the general Midi sounds stored in the VS1053.

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

Record your voice using Arduino and ISD1820. This is a very simple project which takes less than 10 min and < 8$.
