Password based door lock system using arduino.

Just thought of making a password based door lock system in which you can enter the password via the keypad. 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 simple arduino project. As thefts are increasing day by day security is becoming a major concern nowadays.

The simply compile it then finally upload it to the atmega328 microcontroller. The entire project is controlled by using the arduino. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. A 4 4 or 4 3 keypad can be used to enter the desired password.

The password based door lock system allows only authorized persons to access the restricted areas. It will open your door only when the right password is entered. In this project we will learn how to make password based door lock security system using arduino keypad. So a digital code lock can secure your home or locker easily.

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. After that place the arduino board to the bottom side of the lock and connect all the wires according to the schematic. The code for password based door lock security system using arduino keypad is given below. Download the library for keypad h from below.
