Automatic Door Lock System Project Using Arduino

I have already posted an tutorial about the same project with bluetooth module you can refer.

Automatic door lock system project using arduino.

The aim is to control a door lock without keys and using a smartphone to accomplish this. This is a simple arduino project. An automatic door opener system is a simple project based on pir sensor and arduino which automatically opens and closes the door by detecting a person or object. The default pins for serial communication on the arduino uno are pin 0 rxd and pin 1 txd of the board but we are going to use other pins for serial communication.

In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. Password based security system using arduino keypad. Where as soon as a person approaches the door at about 2 or. This is a simple project made with the arduino uno r3.

Smart bt door lock simple arduino. That s how we got started to develop this project and are very happy with the way it finally looks. For this project we will use the softwareserial library in the code. This circuit is mainly used for an interfacing of rfid reader with an arduino.

As thefts are increasing day by day security is becoming a major concern nowadays. The aim is to control a door lock without keys but using a smart phone instead. So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno. You might have seen automatic door opener systems at shopping malls cinemas hospitals etc.

The automatic door lock system circuit diagram using an arduino is shown below. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. In countries like india such automatic systems are not cheap by any yardstick. In this project we will make a digital door lock system with keypad using arduino uno it will open your door only when the right password is entered and it will start beeping when a wrong password is entered.

It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. The circuit of this project uses three separate parts namely a reader a controller and door lock. Just thought of making a password based door lock system in which you can enter the password via the keypad. This project can be enhanced by connecting an lcd display to display the outputs.

As thefts are increasing day by day security is becoming a major concern nowadays. So a digital code lock can secure your home or locker easily.
