A custom audio visualizer printed circuit board (PCB), designed using KiCad and programmed with Arduino and C++, featuring interrupt-driven C++ logic to synchronize RGB LED animations with real-time ...

[Isaac] sent in his mashup build of a LED cube combined with a graphic EQ meter. The build is fairly simple and from the video we can tell that his build would be a great installation in a dubstep ...

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), ...

Flashing LEDs are all well and good, but they’re even better if they can sync up with ambient sounds or music. [mircemk] has built the LUMAZOID visualizer to do just that, relying on some staple maker ...
