// Using the LED bar and the rotating potentiometer, create an application that replicates a volume
// control dial. Meaning as the potentiometer dial is rotated clockwise, an increasing amount of LEDs
// light up indicating higher volume. Conversely, as the dial is rotated counter-clockwise, LEDs are
// turned off.
