Arduino Interrupts not working

I would suggest every user to learn the "interrupt manangement" as quick as possible

Objection - It makes no sense to deal with interrupts until you have learned the basics of cleanly structured and blocking-free programming. No book on programming starts with interrupts.

They paint themselves into a corner with poorly-organized, blocking code and then hope interrupts will rescue them. They won't.
