using Arduino. I'm trying to set Date/Time manully by the keypad to print that on LCD . i made the code but need some help to make it work. here is the code below :

#include

// The wire library is sometimes need you can remove it unless your compiler complains

// about it as a missing library

#include

// Pin Definitions for the LCD Display

#define lcdSDAPin A4

#define lcdSCLPin A5

#define lcdAddress 0x3F

#define lcdColumns 16

#define lcdRows 2

//Pin definitions for the 4x4 matrix keypad

//UPDATE the numbers to match the pin connections from YOUR keypad to YOUR Arduino

#define Row1Pin 9

#define Row2Pin 8

#define Row3Pin 7

#define Row4Pin 6

#define Col1Pin 5

#define Col2Pin 4

#define Col3Pin 3

#define Col4Pin 2

char customKey;

const byte ROWS = 4; // Four rows on the keypad

const byte COLS = 4; // Four columns on the keypad

// Define the keymap for the keypad

char keys[ROWS][COLS] = {

{ '1', '2', '3', 'A' },

{ '4', '5', '6', 'B' },

{ '7', '8', '9', 'C' },

{ '*', '0', '#', 'D' }

};

byte rowPins[ROWS] = { Row1Pin, Row2Pin, Row3Pin, Row4Pin }; // Connect to the row pinouts of the keypad

byte colPins[COLS] = { Col1Pin, Col2Pin, Col3Pin, Col4Pin }; // Connect to the column pinouts of the keypad

// Initialize the keypad object

Keypad customKeypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS);

// Set the pins on the I2C chip used for LCD connections:

// addr, en,rw,rs,d4,d5,d6,d7,bl,blpol

LiquidCrystal_I2C lcd(lcdAddress, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE);

unsigned long timeNow = 0;
