Nov, 2010 hello again guys, im having another problem on how to make my counter count 10 states 09 only, and i want to use a logical and diode junction, my method is to connect 2 diodes to the corrosponding 1s which are q0 and q3 and the output is connect to up pin so that the up stays high no matter what the timer 555 output is and stays so until i use the down pin by another circuit later, weird.
