Interactive Scrolling LED Text

We will create 3 examples, with the primary one we are going to justify the fundamental rule of the MAX7219, within the second example we are going to see however the scrolling text on the 8×32 light-emitting diode Matrix works, and within the third example, we are going to manage them via Bluetooth and a custom build robot application.
