Hi all,
I, too, am making an up/down counter using the 40192 and have found this thread very helpful. I have everything working but the counter counts when the push button is released. I saw the circuit proposed by Sgt. Wookie that counts when the button is pushed, but alas I must use a SPST pushbutton. Does the 555 trigger circuit shown in the previous post accomplish that (increments counter when pushed)? Thanks!
