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. 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. A 4 4 or 4 3 keypad can be used to enter the desired password.

So a digital code lock can secure your home or locker easily. The password based door lock system allows only authorized persons to access the restricted areas. This is a simple arduino project. You can simply copy paste the code using arduino ide.

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. As thefts are increasing day by day security is becoming a major concern nowadays. After that place the arduino board to the bottom side of the lock and connect all the wires according to the schematic.

It will open your door only when the right password is entered. The entire project is controlled by using the arduino. In this project we will learn how to make password based door lock security system using arduino keypad. The code for password based door lock security system using arduino keypad is given below.
