I need to make a timer circuit to range between 1second and 12 hours (will need a display) Im not on here for some one to do the work for me but point me in the right direction otherwise i wont learn.... So far ive sorted out a clock and have been looking at binary counters.

Had an idea, need some way of programming a set time and use a binary counter to decrement to zero at which point it will initiate my polarity change circuit.
