The entire project is controlled by using the arduino.
Password based door lock system using arduino and keypad. Just compile it and finally upload it to the atmega328 microcontroller. After learning how the 4 4 keypad with arduino works we can now demonstrate how this keypad can be used to make a simple keyword based door lock. It will open your door only when the right password is entered. On scanning the right tag and on entering the right password it will send us a confirmation message that the door has opened.
About the 4 4 keypad. We have used eeprom in the arduino to store the password in it. So a digital code lock can secure your home or locker easily. A 4 4 or 4 3 keypad can be used to enter the desired password.
The code for password based door lock security system using arduino keypad is given below. You can easily copy and paste the code using the arduino ide. In this project we will learn how to make password based door lock security system using arduino keypad. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.
Password security lock system using arduino keypad program code. The code is provided for a password security lock system using arduino keypad project. The password based door lock system allows only authorized persons to access the restricted areas. The default password stored in it will be 1234.
As thefts are increasing day by day security is becoming a major concern nowadays. The setup is as shown below we have only added leds to show the state of the lock. Download the library for keypad h from below. The simply compile it then finally upload it to the atmega328 microcontroller.
