Mini LED Matrix Audio Visualizer


In this project, you'll learn how to build an audio reactive LED matrix using the 13x9 IS31FL3741 LED matrix and Feather Sense nRF52840 board with CircuitPython. The Feather Sense nRF52840 features a built-in PDM MEMs microphone for audio input. Audio is sampled via the onboard PDM microphone. The sampled data is then visualized with color.
