//***************Arduino Code from Video*************************************
/* This Arduino sketch was made for a tutorial entitled "Building a Fun and Scalable RGB LED Display Part 1" for the ForceTronics YouTube Channel
* This sketch was leveraged from an example with the Adafruit NeoPixel library.This sketch was used to compare performance of an Arduino UNO versus
* the Altrium Sno FPGA based Arduino for controlling the ADafruit NeoMatrix. This sketch randomly changes each pixel's brightness and color in a timed
* loop.
* This code is free for others to use and modify at their own risk
