The state machine article posted a few days ago was really interesting so the debouncing technique has been added to the project as opposed to the timer debouncing that was there before. This also allows for more functionality in the future so reply with comments if you would like to see anything specific added and maybe it will be available in the future. 

See the links below for the Hack a Day article as well as the creators GitHub page. Be sure to check out his video as it is very interesting and has a lot to learn from it.
