Quite some time ago, as an undergraduate student, I took a course in Digital Circuits. It was a very interesting course, but looking through the textbook (I would look at my notes if I could find them...), I am unable to solve this problem I have:
I want to design a circuit that will apply an electric current for a period of time (controlling the length of time would be nice...), then "open a switch" (either on the IC or through a diode or something) to allow an electric current to flow for a period of time (again, control here would be nice).
Does that make sense?
I'd like to keep things simple: IC(s), wire, battery (and maybe diode). I will need to know what kind of IC(s) to use, and how to hook things up/program things.
In advance - Thank you for any/all assistance.
