Password Based Door Lock System Using Arduino And Keypad

The setup is as shown below we have only added leds to show the state of the lock.

Password based door lock system using arduino and keypad.

Password security lock system using arduino keypad program code. So a digital code lock can secure your home or locker easily. It will open your door only when the right password is entered. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

You can easily copy and paste the code using the arduino ide. About the 4 4 keypad. We have used eeprom in the arduino to store the password in it. The code is provided for a password security lock system using arduino keypad project.

The default password stored in it will be 1234. The password based door lock system allows only authorized persons to access the restricted areas. As thefts are increasing day by day security is becoming a major concern nowadays. Just compile it and finally upload it to the atmega328 microcontroller.

After learning how the 4 4 keypad with arduino works we can now demonstrate how this keypad can be used to make a simple keyword based door lock. On scanning the right tag and on entering the right password it will send us a confirmation message that the door has opened. The code for password based door lock security system using arduino keypad is given below. In this project we will learn how to make password based door lock security system using arduino keypad.

You can simply copy paste the code using arduino ide. The entire project is controlled by using the arduino. A 4 4 or 4 3 keypad can be used to enter the desired password. Just thought of making a password based door lock system in which you can enter the password via the keypad.
