The setup is as shown below we have only added leds to show the state of the lock. You can simply copy paste the code using arduino ide. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. The code is provided for a password security lock system using arduino keypad project.

We have used eeprom in the arduino to store the password in it. A 4 4 or 4 3 keypad can be used to enter the desired password. So a digital code lock can secure your home or locker easily. Working of rfid and keypad based door lock and alert system using arduino on scanning the wrong tag or on entering the wrong password it will send us an alert.
