A digital clock circuit will be designed. Clock LEDs (00-23) in your design, There will be minute leds (00-59) and seconds leds (00-59). Each LED as the output of a counter It will be accepted and will be counted within the specified interval. When the second reaches 59, the minute When the minute reaches 59, it will trigger the clock, that is, increase it. Use it in your circuit below The necessary rules are given.

MOD-60 counter for seconds, MOD-60 counter for minutes, and MOD-24 counter for hour. is required. State table for the design of MOD meters and the status table of your flip flops depending on this table. The equation will be deduced.

Any flip flop you want can be used. (DTJK)

Since there is a 6-bit input in the MOD-59 counter, the use of karnough map is quite easy. It will get harder. Therefore, in Table method, Karnough table or Minterm form You can design your circuit any way you want. The important thing is that the circuit is correct is the work.

Counter outputs can be displayed on 7 segment LEDs instead of bit format as follows (Optional); The representation of 43 in bit form is as follows in my login instead of 101011 it could be.
