Hello,
I have found this link: http://www.gammon.com.au/forum/?id=10945 with great info on reading and using buttons with interrrupts.

I am trying to post a reply in that forum. Is that possible?
It is not clear to me, if I would use 5 buttons, how I could tell which button is pressed. Any info on how or where to post a reply would be great.

Thanks for a helpful post.

Please post Arduino-related questions to the Arduino Forum or to StackExchange: Arduino. This saves splitting questions and answers between this forum and the Arduino ones.
