I have programmed a keypad matrix (which is finally correct) and Im currently using a the Password library to turn an LED on when the correct password is entered (in time it will trigger a relay or something but I am having a steep learning curve using the code!)
My question is that every time i press a key it is recorded as 3 presses in the serial monitor. I can get around this issue by extending the passcode (eg 111222333444 instead of 1234) but I wondered if there was a simple fix?
I am using 0 as the reset and 9 as the guessPassword so I would enter 012349 to turn the light on
Any advice would be greatly appreciated. I have attached the .ino file for reference
