20141031: major bug fix; added multi-button support with a new 5-button-reader example!
20140531: first release.
|Misc. push buttons which can greatly|
benefit from digital debouncing.

I wanted a simple and universal, yet very powerful & reliable library to read a button or switch in such a way that I can easily implement toggled actions and momentary actions, know the true, debounced state of a button or switch at any given time, and specify whether I want an action to take place when the button is *pressed* or *released.* This library makes implementing all of these things easy for me, and I now use it on all of my projects that require reading a button or switch, so I wanted to share it with others. Hopefully you find it useful too. Check out the included examples.
This code is an elaboration of, and library form of, the main Arduino-sponsored "Debounce" example found here. Thanks to David A. Mellis, Limor Fried (LadyAda), and Mike Walters for writing that excellent and well-thought-out example code.
(Optionally) donate, & download via the link just above, or by clicking here then choosing the appropriate download. Install the library into the Arduino IDE (using Sketch --> Include Library --> Add .ZIP Library), then run the examples to see how to use the library.
