Here I present you a 32 Band LED Audio Spectrum Analyzer made with a Arduino Nano and a MAX 7219 4x LED Dot matrix panel. 4 patterns were included and you can cycle through those with the push button.
python code to analyze audio spectrum using the LED matrix of the Raspberry Pi sense HAT This code is a modification of https://www.rototron.info/raspberry-pi ...
The circuit has been designed to create a spectrum analyzer that will provide an analysis of a sound to determine at various frequencies, the volume of sounds that make up the overall sound spectrum.
