8×8 LED Matrix MAX7219 Tutorial with Scrolling Text & Android Control via Bluetooth

In this Arduino tutorial we will learn how to control 8×8 LED Matrix using the MAX7219 driver and the Arduino board. We will make three examples, with the first one we will explain the basic working principle of the MAX7219 , in the second example we will see how the scrolling text on the 8×8 LED Matrix works, and in the third example we will control them via Bluetooth and a custom build Android application.
