I keep getting a message that says I didn't define the variable "second", "hour" and "minute" but I did already defined it earlier. Any help would be appreciated. Thank you! #include <Wire.h> #include <LiquidCrystal_I2C.h> #include <Keypad.h> //#include <iostream> //#include <string> LiquidCrystal…

These int second = 30; int minute = 0; int hour = 0; are only visible within the enclosing { braces }. If you mean to have one variable for each of those three things, you can use global varaibles, those wou,d be defined once, usually at the top of a program. Then just use them…
