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.Guide: https://learn.adafruit.com/mini-led-matrix-audio-visualizerFeather Sense nRF52840https://www.adafruit.com/product/4516 LED Matrix 13x9 IS31FL3741https://www.adafruit.com/product/5201 Code by Liz Clark on GitHubhttps://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Feather_Sense_Audio_Visualizer_13x9_RGB_LED_Matrix/waterfall_visualizer/code.pyCode by Phil B on GitHubhttps://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Feather_Sense_Audio_Visualizer_13x9_RGB_LED_Matrix/audio_spectrum_lightshow/code.py3D Files on Thingiversehttps://www.thingiverse.com/thing:4983214/ 3D Files on PrusaPrintershttps://www.prusaprinters.org/social/3814-adafruit/prints uLab Learn Guidehttps://learn.adafruit.com/ulab-crunch-numbers-fast-with-circuitpython3D Parts Library on GitHub https://github.com/adafruit/Adafruit_CAD_PartsVisit the Adafruit shop online - http://www.adafruit.com-----------------------------------------LIVE CHAT IS HERE! http://adafru.it/discordAdafruit on Instagram: https://www.instagram.com/adafruitSubscribe to Adafruit on YouTube: http://adafru.it/subscribeNew tutorials on the Adafruit Learning System: http://learn.adafruit.com/-----------------------------------------
