# ESP32-MSGEQ7

This M5Stack/MSGEQ7 Audio spectrum Visualizer is an interpretation of jollyFactory's example code provided with the MSGEQ7 Audio spectrum Visualizer Kit:

  - https://www.tindie.com/products/nick64/jf-audio-spectrum-visualizer-board-basic-kit/

It was first adapted to work with ESP32-Wrover-Kit instead of Arduino Nano.

The proto shield idea came after observing the dimensions similarities with the M5Stack proto boards.



Et voilà 



Proto board Wiring

------------------



  - Reset and Strobe are connected to OUTPUT pins on the ESP32.

  - Left band and Right band are INPUT pins on the ESP32

  

Important note: The example code uses pins 25 and 26 and assumes the internal speaker is removed or had its wires cut.

If you aren't planning to do so, just pick two other pins :-)
