Simple Subscriber counter display using WEMOS D1 Mini and MAX7219 LED Matrix for scrolling text

Erics Wemos D1 Mini displaying YouTube Subscriber Count with MAX7219 LED Matrix Displays

Original Library here https://github.com/squix78/MAX7219LedMatrix but contains no function to rotate for my displays

Brian Lough's library contains rotate: https://github.com/witnessmenow/MAX7219LedMatrix

Brians doesnt work with Wemos D1 mini unless you comment out this line https://github.com/witnessmenow/MAX7219LedMatrix/blob/master/LedMatrix.cpp#L34 Done in the cpp file contained with this sketch

Eric originally followed this tutorial here for the YouTube API info etc: http://www.joeybabcock.me/blog/projects/arduino-esp8266-live-subscriber-display/

Ensure you use the correct JSON Library: Go to Sketch, Include Library, Manage library. Search for ArduinoJson Click Select Version. Choose 5.13.4
