I was able to produce this circuit with a 4x4 matrix keypad, on a breadboard. The keys sometime repeat, due to bouncing and occasionally the bounce will produce two different keys from the same column. The first key pressed does not show up in the first space on the first line, it always shows up in the second space, and after filling the top line with numbers it take 13 or more keystrokes, before it will start working on the second line. Other then that I am pretty happy with the results so far. Thank you.

Make a delay after press Because of delay it is avoiding key bounce technique

@seshanandareddy60786 жыл бұрын
After first row scan over , you have keep R1 logic as 1 otherwise columns keys become zero ,even if you operate keys R1, so R1 you to make logic one compulsory.
