#This script is like a quiz thing, if one button is pressed it will light up an LED by it and will disable the other LED by the other Button until a quizmaster switch is pressed.
#LEDs connected to GPIO pins 14 and 15, buttons connected to GPIO pins 12, 13, and 16, pull down resistors are not needed.
#Be sure to use 150Ω resistors between the LEDs and ground
