# This code assumes that you will use the LED with another code in which case you can
# just call the function to have the led on/off when required
# first we need to import the libraries that are needed to turn the led on and off

#do not do this if you have already done it with another code recipe you're combining
#clear up the current board setup.

#Now we will set the pin number we will use to send the signal to the LED

#Set the LED on... Turn to False to command it off again.
