Description of On-Off Button:

The on-off button uses two functions.

The first, checkButton(), detects the moment the button goes from unpressed to pressed. If this is the case, it activates the second function.

The second function is flipButtonState(). When used, it flips the state of an on-off boolean. For example, if the boolean is false before the function runs, it will become true after. If it was true first, it will become false.

The boolean controls whether or not the LED’s are off or updated by the pots.
