If you are looking to display more than just an LED or a 7 segment, or even “scroll” a text or bit image, the 8×8 Dot Matrix is the perfect board. This is possible by the power of the MAX7219 chip which does all the work for the “multiplexing” you need for the circuit.
You may also connect more of this boards to have a long scrolling text in your projects. Check out this link Controlling a LED Matrix with MAX7219/MAX7221 for using this MAX7219 board with the Arduino. Check out the others links also below. In the tutorials and links section.
