Audio/Music Spectrum Visualizer Using Arduino & Dot Matrix Display

Today we will learn how to create an Audio Spectrum Visualizer using an Arduino and a MAX7219 Matrix Display. In this project, we’ll show you how to build a circuit that can visualize the frequency spectrum of both periodic and speech signals in real-time, and display it on an LED dot matrix display.
