Design a digital watch (12 hour or 24 hour) for displaying HH:MM:SS, using counters. You can use 8-bit LED display(s). ​

​

You are my friend and a friend helping a friend so do this homework
The point at which I could not do it is how do I make the clock back to zero when you get to 24

I'll give you two degrees of grades

 

So, post your work so far and we can help you work through the problems you seem to be having.

 

One thread is enough, keep the discussion over here please.

 

Search projects, seen one the other day. Let me try find the link

This won't get you very far, here. We won't do you're homework for you no matter how much you try to claim that we're your "friends" and that "friends" do this for each other. If that is what you really want, then you have no business in this field at all. Do everyone, yourself included, a big favor and go find something that captures your interest sufficiently that you WANT to learn the material involved in that field. Don't kid yourself into the delusion that finding someone to do your work for you will have done you any favors at all. Even if you find, or pay, someone to do that right up to the day you have a diploma in your hand it will have done you no good, because then you will have to compete with all of the other people that have diplomas in their hands. Just remember, you may not love engineering, but you will be competing against people that do.
