This project is an interactive Arduino-based piano that plays musical notes and a song stored on an SD card. It also includes a sound spectrum visualizer using an LED matrix, which reacts to the audio ...

A real-time audio spectrum visualizer built using an Arduino Uno and an electret microphone module. The system converts live audio into visual LED patterns, demonstrating both signal processing and ...

This proof-of-concept is just waiting for you to put it to good use. [Mike Tsao] wrote an Arduino sketch that lets him decode incoming audio data which could be used to program the device. He’s ...

Have you ever wanted to know what is inside a digital audio mixing console? Or have you already programmed some MP3-player based on an ESP32 and the great Arduino libraries, but without the option for ...

We’ve all been there: after assessing a problem and thinking about a solution, we immediately rush to pursue the first that comes to mind, only to later find that there was a vastly simpler ...
