Need help with an issue please.
This circuit is suppose to spell out "CLUE" and repeat. I can get it to work great on multisim. But when I physically build the circuit. It doesn't work.
It spits out a seemingly random "CLCECULECLECU" Those letters are in no particular order everytime. It's something different everytime other than "CLUECLUE..."
I checked my wiring ALOT, over and over....then checked it over and over again.
I swapped both 74LS76 IC's, samething. Swapped them again with another pair, samething.
I swapped the 7 Seg display, samething.
I moved the circuit to a different part of the breadboard, and alas, same thing again.
I know the diagram is correct, and it works 100% on Multisim.
Any ideas?
