Password Based Door Lock System Using Arduino And Keypad

Just compile it and finally upload it to the atmega328 microcontroller.

Password based door lock system using arduino and keypad.

So a digital code lock can secure your home or locker easily. 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. The entire project is controlled by using the arduino.

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. In this project we will learn how to make password based door lock security system using arduino keypad. As thefts are increasing day by day security is becoming a major concern nowadays. The code for password based door lock security system using arduino keypad is given below.

The simply compile it then finally upload it to the atmega328 microcontroller. About the 4 4 keypad. You can easily copy and paste the code using the arduino ide. 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. 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. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. On scanning the right tag and on entering the right password it will send us a confirmation message that the door has opened.

The default password stored in it will be 1234. Password security lock system using arduino keypad program code. Download the library for keypad h from below. The code is provided for a password security lock system using arduino keypad project.
