Password based door lock system using arduino.

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. First place the lock with four screws. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

The simply compile it then finally upload it to the atmega328 microcontroller. The password based door lock system allows only authorized persons to access the restricted areas. Download the library for keypad h from below. A 4 4 or 4 3 keypad can be used to enter the desired password.

After that place the arduino board to the bottom side of the lock and connect all the wires according to the schematic. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. You can simply copy paste the code using arduino ide. This is a simple arduino project.

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. This is a door lock security system made with arduino. As thefts are increasing day by day security is becoming a major concern nowadays. The entire project is controlled by using the arduino.
