Hello, newbie here..
I have an assignment project for my study. I have to build a 10 minutes countdown timer that only/must using analog ICs. I have tried many design from internet like using ic 74192 or combination of JK flip flops. Actually the problem is I don't know how to make the timer running in 10 minutes by setting the IC 74192.
Things I have done:
- Made clock by using ne555
-I know how to using 7 segment and the BCD decoder
-I have tried designs below
