YouTube video for this project: Arduino BCD Conversion Interfacing MAX7219 LED Display Controller.
This is very similar to two related projects with Arduino and the MAX7219. In this case I demonstrate how to convert from an integer value to binary coded decimal. (BCD) This is done without the use of any micro-controller specific libraries for functions.
The first four digits on the display will count from 0000-9999.
