Hi everyone. We were asked to make a score board that can increment 1,2,3 and decrement 1. With timer using only logic gates It should add 1, 2 or 3 not in the series. ex. if it display 4 you push the button for 2 increment it will be 6 also if you push the button increment of 3 it will display 9. And Yes only logic gates are required for ex. if we used flipflop it should be in logic gates form. By the way it is from 0-999

 

Please, one thread per topic. Otherwise chaos ensues.
