Hello,im student and i must finish project.I should make clock with IC's and i created signal,second and minute but my problem i cant make 24 or 12 counter for hour.When i show on display i see 0,1,2...24 after AGAIN 2 why cant i see 0.I watched all counter videos in yt.In 12 counter i see 0 1,2..12 after that 2.I changed all components and no change

We need a schematic to see how you’ve wired your counter.

 

You are giving us nothing to work with. You need to provide a schematic of what you currently have.

 

With two, decade counter chips, you can display 00-23 and decode the output, 23, so you can reset it to 00 when the minutes are 59. So what is the problem?

That depends on whether he is doing a synchronous or an asynchronous rest -- which underscores why we need more information, preferably a schematic.

 

Welcome to AAC!

Are you allowed to use any IC's you want? Are you supposed to make a 12 and 24 hour clock.

FWIW, hours in a 24 hour clock don't display numbers 00 .. 23, not 24.

Are you breadboarding the circuit? Or just simulating. As others have already mentioned, we need a schematic and a description of what isn't working correctly.

Typing and thinking at the same time can be a challenge. It happens to me all the time.
