A simple Lightshow, programmed in matlab. This project allows you to calculate a lightshow in matlab from a local .mp3 file. As an output device you can use a Arduino or NodeMCU (i would prefer the NodeMCU, to get a fast Serial communucation).
In this code i use the NodeMCU:
Vin for 5V power
GND for Ground
D6 for LED communication
.
