    - Button = 1 decrement
    + Button = 1 increment
    RESET Button = zero display

    displays = 7 segment, com cathode

    ^^ I once had requested some time ago, a similar circuit like THIS one.. but instead I got FLAME replies :mad: :p

    nice one profahmet ;)

    I can guess your using a lookup table...

    how about adding a laeding zeroes blanking...that would make your project neat :cool:

    very neat , buttons can also be replaced with nominal timers and counters making your project ideal for anything

    Dear Profahmet,

    I put this circuit on the bread board to test it does not work. I measure the 1234 it is positive voltage out from the pic pin 17,18,1,2 instead of negative. As you said used the common cathode, is there a mistake. Please reply. Thanks

    Why is so much "thank you" for something that does not work?

    Trolling again, eh?
