up down counter circuit 1-5

[leojr]

anybody i need help
i was assigned by our teacher to create a simulation circuit
using multism that will count from 1-5 and vice versa
by using 74ls247, 74ls192 and 555 timer
please help i don't have idea how to limit the count

Specifying the problem clearly is the first step. Do you mean counting 1-2-3-4-5-1 ? What is vice versa? Counting down? If so, how to decide about counting direction?

Technically, the asynchronous load (preset) of xx192 can be used to limit the count range. The part doesn't offer a means for a "clean" synchronous solution, thus I assume, it's not required in this case. You most likely need additional logic gates to implement the counter range, "jump" from 6 to 1.

The circuit will up count and down like this 1-2-3-4-5-4-3-2-1 . . .
there must have tackle switch one for up counting
and another one for down..
could you please help me
it's hard for me you know
please, if possible attach schematic

The below specifications are mutual exclusive, I think. Either the count direction is reversed automatically, or by a manual switch.

Posting ready-made homework solutions isn't helpful in my view.
