Two BUTTONS two LEDs
Uses Two BUTTONS and LEDS to activate functions
This code uses two LEDs and two BUTTONS. The second LED is on
pin 13. Pin 13 ALWAYS has a LED connected to it, and is noted
with an L on your Arduino UNO. Pressing the momentary switch 1
will either turn on an LED or run a special function that
blinks an LED with a set patter. Pressing momentary switch 2
will do the same, but output to a different LED or function.
