LED Matrix Essentials with the MD MAX72XX library
LED Matrix Essentials
In this video we take a look at a 4 unit 64 LED Matrix controlled by the MAX7219 chip. Because there are so many of these units available and all are wired differently we have to be very careful in choosing a library.
We are using the MD_MAX72XX library because it has the capabilities to adapt to the different wiring. The matrix modules all connect to the Arduino through a 3 wire SPI interface (MOSI,CLK,CS) and two power wires.
The module that we use in the video is the WangDD22 and is available from Amazon. If you decide to buy one, please use this link http://amzn.to/2oCIFl3. I get a few cents from every sale.
The MD_MAX72XX library can be downloaded here: https://github.com/MajicDesigns
More videos on how to use these modules and this library are on the way.
