listing program:

// Include the Keypad library

#include <Keypad.h>
#include <LiquidCrystal.h>
// Constants for row and column sizes
const byte ROWS = 4;
const byte COLS = 4;
LiquidCrystal lcd(A0, A1, A2, A3, A4, A5);
// Array to represent keys on keypad
char hexaKeys[ROWS][COLS] = {
 {'1', '2', '3', 'A'},
 {'4', '5', '6', 'B'},
 {'7', '8', '9', 'C'},
 {'*', '0', '#', 'D'}
};
// Connections to Arduino
byte rowPins[ROWS] = {9, 8, 7, 6};
byte colPins[COLS] = {5, 4, 3, 2};
// Create keypad object
Keypad customKeypad = Keypad(makeKeymap(hexaKeys), rowPins, colPins, ROWS, COLS);
void setup() {
 // Setup serial monitor
 Serial.begin(9600);
 lcd.begin(16, 2);
}
void loop() {
 // Get key value if pressed
 char customKey = customKeypad.getKey();
 if (customKey) {
 // Print key value to serial monitor
 lcd.setCursor(0, 0);
 lcd.print("Tombol :");
 lcd.print(customKey);
 }
