We should also warn the Student Picster about that 10 Ft. wired DIRECTLY 
to the INTERRUPT PIN with a 10K pullup in the bottling factory with all 
those 3 phase 220 and 440 volt motors running his conveyor!  Optos anyone?

I am disappointed the project was just on paper!

He would learn a lot more than he did in his class if he had to set his 
design up at the job site.
He never would tell us if he has been using SIM?
