Hi,
I want to limit the input voltage to a project, the input will be connected directly to a pin on a PIC, I would like to have as wide a voltage range as resonably possible, is there a simple way to do this like a zener or IC or something?
I want this pin to be a general purpose input so the user can attach say 12v or 24v etc. to it and I would see this as a digital '1' in my code without damaging the PIC.
