My project is showing the Car Park Slot from 99 to 00. So i just design the 1st stage of the circuit first.
I was design the Up/Down JK flip flop using the logic gates, but when the decimal until 9 it will continues to A,B,C,D,E,F then back to 0.
The problem was:
1. i need from 9 to 0 only or 0 to 9 only, the A until F NO NEED to show.
2. Because have TWO digit need to showing so how should i connect it from one digit to two digit. Which mean that 99, 98, 97, 96, 95......until 00.Or 00, 01, 04,,06,,56 and so on
