So I'm working on up and down counter and I'm stuck. So I need to make it automatic; in that it goes to 7 and straight starts going down. I have no single clue how to do this. I also somehow need to make it double digited after making it work but I have no idea how to. WELP!
I'm using a 74192, 7447 and other components. Couldn't attach the file cuz the format isn't supported.

 

First, it counts to 7 and then counts down. Why do you need double digits?

Wanted to ask my teacher the same thing!

 

Go ahead and ask him. And let us know the answer.

In that case, thread moved to Homework Help.

I think the key is that he will need to add a second digit AFTER he gets the one-digit version working. Most likely, the second version will count to a higher value before counting back down. That way the student is forced to tackle the big problems as two different smaller problems.
