How to make an extremely simple but visually effective VU meter at 0.9 inches OLED displays SSD 1306.

Using ultrasong PWM frequencies, the Arduino can now produce square tone() waves with 256 volume levels with nothing but a speaker!

In this video I explain how you can use an Arduino to make music using just a speaker and a resistor.

An Arduino based MP3 player with 30 levels of volume adjustment, 5 levels of EQ adjustment, and a pretty cool retro looking UI.

Giorno's Theme Song (il vento d'oro) on Arduino. The project utilizes the tone() function of the Arduino to produce the notes of the song in

I created an alarm clock using a motion detection sensor so that you're not able to just hit the snooze button and go back to sleep.

Very simple audio analyzer with changeable visual modes.

Just another Pro micro Volume Knob Setup with POTENTIOMETER

Theremino is a theremin built with an Arduino UNO and two ultrasound sensors.

How to play audio file by using DF Player Mini.

We want to help people who are unable to communicate verbally and cannot use sign language by providing a wearable “eye-to-speech" solution.

Build an Arduino organ with Kinder Surprise, some resistors and wires and learn how to play music with the electrical capacity of your body.

FM radio built using Arduino, RDA5807M, Tiny RTC, PAM8403 class D amplifier modules, and TR028 touch panel.

How to make Welcome Audio by using PIR sensor

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 is for making an audio (music) frequency spectrum analyzer / visualizer using Arduino, based on Shajeeb's Project.

DTMF decoder without an 8870.

Simple USB to MIDI adapter based on an Arduino Micro or Leonardo, optionally with the ability to filter the MIDI data.

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

In this project, I create a sound location finder. This circuit can be used as the basic building block to a robot that reacts to sound.

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

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

Build a small and robust device with minimal effort, turning any jack plug footswitch into a USB footswitch.
