Password Based Door Lock System Using Arduino And Keypad

It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

Password based door lock system using arduino and keypad.

Download the library for keypad h from below. The password based door lock system allows only authorized persons to access the restricted areas. The code for password based door lock security system using arduino keypad is given below. About the 4 4 keypad.

The entire project is controlled by using the arduino. The code is provided for a password security lock system using arduino keypad project. So a digital code lock can secure your home or locker easily. The default password stored in it will be 1234.

The setup is as shown below we have only added leds to show the state of the lock. A 4 4 or 4 3 keypad can be used to enter the desired password. 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. In this project we will learn how to make password based door lock security system using arduino keypad.

Just thought of making a password based door lock system in which you can enter the password via the keypad. 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. The simply compile it then finally upload it to the atmega328 microcontroller. As thefts are increasing day by day security is becoming a major concern nowadays.

You can easily copy and paste the code using the arduino ide. It will open your door only when the right password is entered. We have used eeprom in the arduino to store the password in it. Just compile it and finally upload it to the atmega328 microcontroller.
