How to make counter using 192's

[judochop45]

I'm trying to make a counter with 192's. I want the counter to count up and down on the same 7 segment display is there a way to do that?

Yes, there is a way to do that. Would this be homework? I assume you mean a 74192 or 74hc192 like this? You don't mention if the 7 segment display is common cathode or common anode? For common anode consider a decoder driver like a 7447. You also fail to mention as to count up and down based on what? Have you got any ideas or a basic schematic?

The seven segment display is a CA and I'm just wondering how to make the 192's count up one digit and down one digit on the same display using 2 PUSH buttons, one counting up and one down.

Eric, Thanks for the help, but I'm wondering is there a way that i can just use the 192's without the 555?

hi,
It really depends upon the method you want to use to clock up and down.?

This link shows push button operation.

I'm going to post a schematic on tuesday, I can't get it to work.
