So many videos i watched for this keypad . Finally i got it from this video . Thank you Sir .

This made the most amount of sense it was simple and informative the favorite part I liked was that you used a Serial monitor

[roncole]

I got into some code that used in LCD screen and a pound sign to reprogram the password and then I tried to program the serial monitor but somewhere in between all the if statements I got them out of the funk order so it only partially worked I think this project will be way better for me thank you
