Hi everyone,
I need help to build a time counter with a 6 digit display HH:MM:SS, The input signal will not be from a clocked circuit, It is rather an open choice from a pulse generator 1 second per pulse, The pulse generator is not part of this circuit, All what I want is the counter with a 6 digit display, The pulse input should be 2 wires or 2 pins, in open status nothing happens, when shorted together it is one pulse or one second until it opens again, The zero reset is by turning off power.
The pulse generator could be a spinning wheel with contacts, when it spins it makes the 2 wires in the time counter close and open fast or slow based on the wheel speed, Although it is just a fun project, It could serve as magnetic tape transport time counter.
