Music Visualization for MQTT RGB LED Strip

You can find the details of the project on my blog.

Essentially I added an effect to my RGB LED strip behind my TV to sync up the colors and brightness to an audio input. To choose an animation you can use Home Assistant to change an effect over MQTT. The LED strip is controlled by a NodeMCU and the audio processing is done with an MSGEQ7.

Was a fun project and will definitely be making more animations for it using the audio.
