Though an input can be from any number of sources, one of the mose common and the easiest to implement, would be a swith. Due to mechanical properties of a switch, when a switch is closed, there is a period of time in which the electrical connection "bounces" between open and closed. To a microcontroller, this "bouncing" can be interpreted as multiple button pushes. Therefore, we must either build a circuit to supress the "bouncing" or we must do so in our software. This is known as "debouncing a switch".
