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 ...

This project creates a real-time audio spectrum visualizer using a microcontroller (Arduino/ESP32), a microphone, and an LED matrix. It analyzes audio input, performs a Fast Fourier Transform (FFT), ...

The ElectroSmash website has featured a new Arduino Audio Meter which takes the form of a programmable guitar pedal based on the Arduino UNO development board. Providing users with the ability to read ...

This one caught my eye on twitter, the Arduino Audio Meter - an Arduino-based device described as spectrum analyser and guitar pedal in one... It's based on the Uno board, to be precise, fitting ...

[El Artis] just finished building an audio spectrum analyzer that uses a character LCD. The uses an Arduino to drive the display, but unlike other meters that use the microcontroller for analysis, [El ...

Thanks to software frameworks and libraries that have become quite powerful over time, even with a compact and inexpensive system, it is possible to achieve complex functions. In this project, we use ...

A stock Arduino isn’t really known for its hi-fi audio generating abilities. For “serious” audio like sample playback, people usually add a shield with hardware to do the heavy lifting. Short of that, ...

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 ...

Makers, hobbyists and developers that enjoy building projects using the Arduino platform might be interested in a new Arduino micro-controller expansion board called the Spectrum I2C. The Spectrum I2C ...
