/*
* 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
