Also notice how the LEDs illuminate in a clockwise direction as you move your finger from
the left to the right across the slider.
5.15. Cover the slider with a piece of paper and then touch the slider (with the paper between
our finger and the slider). Notice how the Difference Count Value changes. Add additional
pieces of paper to increase the thickness over the button. With enough sheets of paper
added, the Difference variable does not rise above the Finger Threshold, and the button
does not register a Hit. With 16 sheets of paper over the slider, the difference bars are very
low and the LEDs do not light up.
