This project is for making a 32-band audio (music) frequency spectrum analyzer / visualizer using Arduino.

This is a another version of a music LED strip using Arduino Nano and an Electret Mic/Max4466 Amplifier.

For use in DIY homebrew radio equipment such superheterodyne single/double conversion receiver, SDR, HAM QRP transceivers or RF generator.

The device that creates beautiful arpeggiated sequences according to the musical theory.

See how an Arduino can be transmit music over AM with only a few lines of code.

Arduino TEA5767 radio with analog meters for showing frequency and signal strength.

Musical instrument for multiple users – with Arduino, nRF24L01, MPR121 and MPU-6050 connected to Pure Data Vanilla.

Build a great sounding FM radio with a cool display using an Arduino Nano and the SparkFun Si4703 FM tuner breakout.

Simple Arduino-based "World Band" radio receiver with very good characteristics.

Nice little all-band radio easy to build.

An easy to build and use stereo RDS FM receiver with RDA5807.

A small noise/drone synth with percussion mode. Made using the Mozzi library and two Arduino Nanos.

Make an alarm sound when the computer stops working.

Live performance oriented sequencer / arpeggiator for multiple synths control.

Make FM Radio full function by RDA5807M and arduino nano. Control by touch button

It is the amazing RGB LED desk light. It will be reacting on the surrounding sound and music and will be playing like a visualizer.

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

Build an "invisibe" expression pedal for your guitar with MCP41010 and Arduino Nano. It's awesome and simple. May the funk be with you.

A simple FM radio with a display that shows the frequency and audio amplifier.

Small and handy radio for your little ones. Let them play their favorite songs or fairytales. And that all in the wooden box!

Piezos used as contact microphones to activate LEDs and shine lights through Samba drums.

Covers all commercial stations with Si4730 IC, plus all amateur radio bands when you use Si4732 or Si4735.

Use your TV's IR remote to control the volume and mute of separate speakers without using the speaker's remote.

Today I will show you how to make your ultrasonic levitator using an Arduino Nano.
