 *  8 Digits LED Seven Segment Display Module based on MAX7219 using Arduino IDE
 *  
 *  updated by Ahmad Shamshiri for Robojax 
 *  On Monday Sep 16, 2019 in Ajax, Ontario, Canada
 *  You can get this code from Robojax.com

 *  Original Libary source: https://github.com/ozhantr/DigitLedDisplay
 *  
 *  Watch video instruction for this video: https://youtu.be/R5ste5UHmQk
 *  At the moments, it doesn't display decimal points. It needs a little work to make it work
