Alarm.pde👎 error: variable or field 'printAddress' declared void

Thank you for this help.

The Arduino IDE doesn't seem to have a problem finding the .h files since it opens them up in separate tabs with the sketch window automatically when I open the sketch.

A "Library" folder sounds like a good idea. Where is it? The documentation is silent on this subject (and also silent on the use of " " ... it only covers the < > and the one example it gives shows part of a path which is odd).

I don't have "disdain" towards the developers. I am just frustrated that there are not better instructions. If they are putting together "Examples", I would expect them to be more complete. I always assume that it is my problem and lack of understanding, not theirs. I am sure that as soon as I am as smart as the developers, everything will work just fine.
