This 8x8 SPI Dot Matrix Module allows you to experiment with dot matrix LED's without all the complicated wiring. The module makes use of the MAX7219 LED driver which handles all the complicated stuff such as multiplexing the LEDs and driving them at the correct currents. What's more, the....
The wiring diagram below shows you how to connect the MAX7219 LED dot matrix display to the Arduino.Note that when using the MD_Parola library, you need to orient the display with the DIN connector on the right, otherwise the text will be printed upside down.For more information seethe sect...
