It's a very nice project. This is exactly what I'm looking for. But one question:
When trying to compile I get the error that the Font_Data.h is missing. Where do I get the file from? Is it a Arduino-library?
That's what I was thinking. I just wanted to mention that in some environments debouncing might be necessary. :-)
Sorry, I don't understand what you mean.
I mentioned this because it may be necessary to debounce a button. You don't need it to demonstrate how a button is evaluated by an Arduino.
