Music and lights are made to go together. They compliment each other in such an amazing way that it is inevitable you will eventually work on a project related to combining them together.
This music visualizer board made by Nootropic Design takes all of the hard work out of making a music reactive project. All that is needed is a WS2812B LED strip and a 5V supply to power it. No documentation for the board is provided unfortunately but from looking at the picture you can just about see it’s rocking an ATMEGA328P at its core. This chip is used in many Arduino boards and so has a huge amount of libraries available for it. Thankfully the source code is available over on Noottropic Design’s GitHub.
Adafruit’s Neopixel library is used to control the LEDs and an FFT library processes the frequency content of the music being played. The programming pins for the chip are broken out although the header is unpopulated. There is nothing stopping you soldering on some header pins and modifying the existing music visualizations!
