We must next create a counter that will track button presses. This counter will let the program know which note should be sounded when blown as well as which NeoPixel and color should be on.

We declare the counter outside of the following while loop so that it doesn’t get reset back to 0 at the beginning of each loop.

#Create a counter for tracking button presses
#Declared outside scope of while loop so it doesn't get reset to 0 at the beginnning of every loop!
counter = 0

#Create a counter for tracking button presses
#Declared outside scope of while loop so it doesn't get reset to 0 at the beginnning of every loop!
counter = 0
