Hello, I have this problem when i simulate the circuit on proteus the counter will stay at 00. I am using ne555 as pulse, 74ls192 as up/down counter. I don't know what is the problem/error on my circuit. Anyone who can help me with this? Thank you for the response.

here is my schematic diagramView attachment 309856

Hi

Just wanted to let you know I drew your circuit with mods in proteus. The circuit basically works.
However, I recommend not using a 555 clock generator for simulation purposes. Instead, use a digital clock generator for the clock signal. I used one with the default settings that worked fine.

 

Hello, so this project is solve, I think the problem is that the proteus can’t simulate it faster coz when I implement it in breadboard the pulse is okay and it is working. Thank you for your response, I really appreciate it.

 

Yes, b

Yes, but we are required to use 555.

 

Your 555 has a few problems:
