/**
 * @file Buttonable2.ino Example on/off control from a button. Similar to the
 * Buttonable example, except this example uses a debounced pin.
 *
 * NB: All that's changes is the `using Button` and `using ButtonList` lines at
 * the beginning of the program to select debounced reading capability.
 *  
 * The built-in LED lights when a button connected between pin 2 and ground is
 * pressed. It uses the internal pull-up resistor within an Arduino for the
 * simplest button connection.
