-Debouncing is implemented in a not blocking way! It is merely done by ignoring a button change within the debouncing time.

-sentence=Arduino library for handling push buttons at INT0 and / or INT1 pin (pin 2 / 3) 
-paragraph=Just attach buttons to pin 2 or 3 of your Arduino - thats it. In you main program define a EasyButton and use ButtonStateIsActive or ButtonToggleState to determine your action. Or use a callback function called once on every button press. If timing does matter, 3 more variables are available: ButtonPressDurationMillis, ButtonLastChangeMillis and ButtonReleaseMillis.
