I designed and built the attached circuit on a breadboard. It only displays number 0 and nothing else. I connected the input pin of 74192 to ground all to no avail. Please help me out. if I should get help on this have make progress a little. Thankshi Exjay,
I don't see your circuit?

Have done that too yet, no changeshi,
Look at this clip from a counter, check your pins on the 74192.
Note the Clear pin 14

560ohmshi Ex,
What is the value of resistor on pin #14 of the 74192.?

hi Ex,560ohms
And tie the resistor to ground in stead of +A 560R resistor on a TTL input [ may not be a low enough value to pull the pin down to a TTL Low state].
Try a 220R.
