Hello, I've build an application using keypad and mount it inside a box. From time to time I receive a beep indicating a fail click in the matrix pad. In other words, there are some interference that I can't understand why. I've tried increasing debounce time. It get better, but still a problem from time to time. Can anyone point a way to improve my code?
