You can Open or Close a lock using keypad with the help of Arduino. All you need is an Arduino, servo motor and Keypad. In this video, we are going to show you how to make an arduino project for home automation to open or close door using a password. Write a program to take input from keypad and open or close the door based on the password received from smartphone. Let’s look at the required components:

Servo servo1;
Password password = Password( “3262” );
const byte ROWS = 4;
const byte COLS = 4;
char keys [ROWS][COLS] = {

{‘*’, ‘0’, ‘#’, ‘D’}
};
byte rowPins [ROWS] = {3, 2, A1, A2 };

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