Password Based Door Lock System Using Arduino

The entire project is controlled by using the arduino.

Password based door lock system using arduino.

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. After that place the arduino board to the bottom side of the lock and connect all the wires according to the schematic. So a digital code lock can secure your home or locker easily. The code for password based door lock security system using arduino keypad is given below.

Just thought of making a password based door lock system in which you can enter the password via the keypad. Password based door lock system using arduino simulino uno schematic diagram read smart phone controlled home automation using arduino the key pad library for the arduino uno available in this linkkeypad this library is setup to do every function for the keypad. Download the library for keypad h from below. It will open your door only when the right password is entered.

As thefts are increasing day by day security is becoming a major concern nowadays. 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. 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. The simply compile it then finally upload it to the atmega328 microcontroller. You can simply copy paste the code using arduino ide. This is a door lock security system made with arduino.
