Install ESP32_FFT_VU

The matrix will run from both a line input or microphone, so choose whichever setup works for you. When choosing the pin for your button, be careful. Some pins on the ESP32 don't have pullup resistors, and if you choose one of these the button won't work! When I was testing, I found that D2 didn't work, but D4 did so I went with that one.
Download this repository and open ESP32_FFT_VU.ino.
You will need the FastLED Neomatrix and EasyButton libraries from the Arduino library manager. Youw will also need the arduinoFFT library. At the time of writing, the library manager version arduinoFFT has a bug which prevents DCRemoval() from working, so download it from the GitHub repository and install it from a zip file.
Watch the video to see how to use it.
To customsise it to your own matrix layout, read about Neomatrix layouts at Adafruit.
