Capacitance is a measure of how much electrical charge something can store. The library checks two pins on your Arduino (one is a sender, the other a receiver), and measures the time it takes for them to have the same state. These pins will be connected to a metal object like aluminum foil. As you get closer to the object, your body will absorb some of the charge, causing it to take longer for the two
pins to be the same.
