tennis score board using jk flip flop

I was planning to make a tennis score board using jk flip flop, is there someone who can give me circuit diagram?

You'll need a lot more than a JK flip-flop. Is this a school project requiring you to use one? If not, forget the flip-flop and go for a PIC or other micro.

Two sets of decade counters maked up of JK flipflops and a set of BCD encoders will do the job.

And he needs a couple of SR flipflops (or mono flipflops) to avoid button bounce.
Can easilly be set up on a breadboard.

That is - if bart's intentions is only to compare two results at scooreboard.

the project requires Logic gates and not microcontrollers. I want the scoreboard to automatically score 1 in the set and count up if the player gets 40? how could that be possible? thanks?

A full scoreboard will be complex using just logic gates. It will have to account for the oddities of tennis scoring (15, 30, 40, deuce, advantage, tie-breaker) to decide when a set is complete, as well as displaying points and sets won for two players/sides.

jayson, I think you should decide if you want a full featured scooreboard or just a couple of counters with resets.

even just a couple of counters with resets its already ok for me.

You need my LOTTO project. It counts to 40.
