Automatic Door Lock System Project Using Arduino

So a digital code lock can secure your home or locker easily.

Automatic door lock system project using arduino.

As thefts are increasing day by day security is becoming a major concern nowadays. That s how we got started to develop this project and are very happy with the way it finally looks. 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. The automatic door lock system circuit diagram using an arduino is shown below.

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 circuit of this project uses three separate parts namely a reader a controller and door lock. For this project we will use the softwareserial library in the code. This project can be enhanced by connecting an lcd display to display the outputs.

It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix. Where as soon as a person approaches the door at about 2 or. 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.

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. Password based security system using arduino keypad. The communication medium will be the internet wifi module esp8266. The aim is to control a door lock without keys and using a smartphone to accomplish this.

In countries like india such automatic systems are not cheap by any yardstick. In this project we will learn how to make the password based security system using arduino keypad. Just thought of making a password based door lock system in which you can enter the password via the keypad. You might have seen automatic door opener systems at shopping malls cinemas hospitals etc.

The aim is to control a door lock without keys but using a smart phone instead. As thefts are increasing day by day security is becoming a major concern nowadays. I have already posted an tutorial about the same project with bluetooth module you can refer. This circuit is mainly used for an interfacing of rfid reader with an arduino.

Smart bt door lock simple arduino. This is a simple project made with the arduino uno r3.
