i hve a circuit that count from 0 to 7 (0000-0111)(motor moving forward) then from 7 to 0(motor reversing).
the circuit that i hve drawn is to detect 7 then it will produce a '1' so tht QA will be '1' and the relay will be on and direction of motor is reversing.
the problem is that once it count down from 7 to 0, after 0 it will count from 7 again. wht gate do i need in order tht after counting down from 7 to 0, it will then count up from 0 to 7 and the cycle repeat.
