The dot matrix that we’re going to use in this guide is a 8×8 matrix which means that it has 8 columns and 8 rows, so it contains a total of 64 LEDs.

The MAX7219 chip makes it easier to control the dot matrix, by just using 3 digital pins of the Arduino board.

I think the best option is to buy the dot matrix with the MAX7219 chip as a module, it will simplify the wiring. You can check the dot matrix at Maker Advisor and find the best price.

You can control more than one matrix at a time. For that you just need to connect them to each other, as they have pins in both sides to extend the dot matrix.
