#Description: It's a basic traditional game of red light, green light, with random numbers to change between the lights!
#When connected properly to a beaglebone black with some LEDs, this program changes the light colors to the respective
#colors of the game. Just something simple to start off with my Python Beagle Bone development. Easy program, but the
#setup was hard.
