Password Based Door Lock System Using Arduino

In this project we will learn how to make password based door lock security system using arduino keypad.

Password based door lock system using arduino.

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. The code for password based door lock security system using arduino keypad is given below. The simply compile it then finally upload it to the atmega328 microcontroller. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

Just thought of making a password based door lock system in which you can enter the password via the keypad. As thefts are increasing day by day security is becoming a major concern nowadays. You can simply copy paste the code using arduino ide. It will open your door only when the right password is entered.
