//Code written by Ryan Chan; it is pretty inefficient, but gets the job done, I challenge you to make it more efficient!

//*IMPORTANT CHANGES IN VERSION 2: LEDs 4 and 5 have been moved to pins 7 and 8 respectively; Buttons 1 and 2 have been moved to pins 12 and 13 respectively. This is to make wiring easier.
