GPIO.setmode (GPIO.BCM)

# So that you don't need to manage non-descriptive numbers,
# set "LIGHT" to 4 so that our code can easily reference the correct pin.

# we need to designate which way we want to use a given pin.
# This allows us to use functions in the GPIO library in order to properly send and receive signals.
