/**
 * @file Buttonable.ino Example on/off control from an Able button.
 * 
 * This shows how Able can be used to create the same program as the built-in
 * [Button example](https://www.arduino.cc/en/Tutorial/BuiltInExamples/Button)
 * included with the Arduino IDE.
 * 
 * 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.
 * 
 * NB: This example uses direct pin reading which is not debounced. Contact
 * bouncing can make the button's signal unstable for a few ms when pressed or
 * released.
