Quick edit/note: Fritzing diagram included of my previous set up used a Mega2560 board. The shield is obviously mounted on an Uno, but the fundamentals of the set up are unchanged, i just have incorporated the buttons and LCD in a shield on top of an Uno instead.
in other words, this fritzing is not what I am actually doing, what I am doing is different.....
