I couldn't explain my happiness when I (with the help of my boss) was able to help some students with their breadboard experiment in Logic Circuits... it should be a NO BIG DEAL coz I am teaching the subject, but its not as simple as the experiments I give to my students...
The display must count up from 0 to 9 while the LED connected to the pulse is blinking. It took me awhile (i'm in the office) and lots of help from my boss and a couple of googling for it to work... it turned out that one of the pins (MR or CLR) MUST BE 0 or connected to ground so that the 74192 will start to count.
happiness ;)
