Password Based Door Lock System Using Arduino

The code for password based door lock security system using arduino keypad is given below.

Password based door lock system using arduino.

The entire project is controlled by using the arduino. First place the lock with four screws. 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. A 4 4 or 4 3 keypad can be used to enter the desired password. Download the library for keypad h from below. You can simply copy paste the code using arduino ide.

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. It will open your door only when the right password is entered. 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. So a digital code lock can secure your home or locker easily. This is a door lock security system made with arduino. In this project we will learn how to make password based door lock security system using arduino keypad.
