NEW GUIDE! Mini LED Matrix Audio Visualizer @BlitzCityDIY @PaintYourDragon @ecken

Learn Guide: Mini LED Matrix Audio Visualizer

In this project, you’ll learn how to build an audio reactive LED matrix using the 13×9 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.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
