16x8 LED dot matrix with MAX7219 module 16x8 LED dot matrix with MAX7219 module
The objective of this project is: to show off the use of the module "MAX7219 dot matrix display module MCU control DIY" And you will need the MaxMatrix libraries files (which are 3):

See in the attached picture the interconnection diagram between Arduino module and MAX7219 module (it was used only 2 MAX7219 modules in this case):

of the module MAX7219 Arduino pin 11 (alternative: pin 8) connected to pin DIN module MAX7219 Arduino pin 10 (alternative: 9 pin) connected to pin CS module MAX7219 GND and VCC (+5V) To expand the number of modules, you should just connect Dout pin of one MAX7219 module with the Din pin of the another MAX7219 module... and so on. The MAX7219 Dout pin is at the top of the module while Din pin is at the botton of the module.
Remembering that you can connect modules as you want, just connecting the output of one module with the input of the other and leaving the other signals in parallel. In the sketch, you should to modify the parameter "maxInUse" for the amount of modules that you will use.
