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. |

|
The 3D printed case houses the two boards and snap fits for an easy assembly. The case features a built-in button presser for using the reset button without having to take it apart. The LED matrix and Feather are secured to a PCB bracket with hardware screws and nuts. |
