Debouncing library for Arduino and Wiring by Thomas Ouellet Fredericks with many contributions from the community : https://github.com/thomasfredericks/Bounce2/graphs/contributors
Basically, the mechanical part of buttons and switches vibrate slightly when closed or opened causing multiple undesired false states (similar to noise). This library filters out these undesired state changes. More about debouncing:
See the bottom of this page for a basic usage example and the "examples" folder for more.
The library is composed of three classes:
Install through your software's Library Manager or download the latest version here and put the "Bounce2" folder in your "libraries" folder.
Please note that the original version of this library (Bounce 1) is included in the "extras" folder of the download but not supported anymore.
The complete class documentation can be found in the "docs" folder or online here.

By default, the Bounce library uses a stable interval to process the debouncing. This is simpler to understand and can cancel unwanted noise.
By defining "#define BOUNCE_LOCK_OUT" in "Bounce.h" (or in your code before including "Bounce.h") you can activate an alternative debouncing method. This method is a lot more responsive, but does not cancel noise.
By defining "#define BOUNCE_WITH_PROMPT_DETECTION" in "Bounce.h" (or in your code before including "Bounce.h") you can activate an alternative debouncing method. Button state changes are available immediately so long as the previous state has been stable for the timeout period. Otherwise the state will be updated as soon as the timeout period allows.
