Combining millis with button sensing

Unfortunately I am not at the level yet to be using libraries

That is absolute nonsense :wink: You already are! Serial, digitalWrite() and heck, even loop() is already from libraries. That's what makes Arduino easy. Only difference, this is a non-standard library. But just go to Sketch => Include Library => Manage Libraries and search for Bounce2, done!

Libraries are there to make life easy, not hard. Although some pore written libraries can be better left alone, Bounce2 is a library that makes life easy :slight_smile:
