I need to make a 24 hour clock with seconds using 7490's, 7447's and 7-segment displays. I have connected the SECONDS display ona breadboard. Then i built a similiar circuit for the minutes part. but when i connected the output of the seconds to the input of the minutes, the circuit doesnt seem to be working. i tried to troubleshoot and fed both circuits with the same clock input, and the display will count between 00-59. So the circuits work but how do i connect them?
pictures or circuit diagrams would be most appreciated =) thanks
