ACircuit Diagram to Interface LED MAtrix display with Arduino Now that we have completely understood how a MAX7219 LED Dot Matrix Display Module works, we can connect all the required wires to the Arduino and write the code to print our desired text on the display. The connection diagram ...
Since the MAX7219 can control a maximum of 64 LEDs, the maximum size dot matrix display it can drive is 8×8 pixels. However, you can daisy chain multiple drivers and matrices together and easily control much larger displays like 8×32, 8×64, or even bigger. Still, you only need three...
