    hi everybody,
    i was looking for a project "Simple combination lock".
    it was a perfect project to give to my teacher but still something else needed.
    it should be a counter with the "NOT GO" LED
    so, if i tried 3 times with a wrong password to give an alarm or any simple signal like another LED .
    i have to give the project today evening so please if any body can help me and i'll be thankfull.

    I've never seen a "NOT GO" LED
    Would be handy on a Time Machine.

    Would it not be an idea to post your current work. We have no clue on how to help you.
