Password based door lock system using arduino.

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. First place the lock with four screws. This is a simple arduino project.

Download the library for keypad h from below. Then fix the bluetooth module at the right place of the lock and add some hot glue to tightly adjust the module with the lock. The password based door lock system allows only authorized persons to access the restricted areas. The simply compile it then finally upload it to the atmega328 microcontroller.

After that place the arduino board to the bottom side of the lock and connect all the wires according to the schematic. As thefts are increasing day by day security is becoming a major concern nowadays. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.

A 4 4 or 4 3 keypad can be used to enter the desired password. It will open your door only when the right password is entered. So a digital code lock can secure your home or locker easily. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
