Smart Door Lock System Project Using Arduino

It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

Smart door lock system project using arduino.

This will signal the arduino to lock the door. In this project we want to make an arduino based system that helps you to make a login section for a door by wifi and solenoid lock. For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3. This is a simple project made with the arduino uno r3.

This will signal the arduino to unlock the door. The aim is to control a door lock without keys and using a smartphone to accomplish this. You can simply copy paste the code using arduino ide. In this post let us build a secret knock detecting door lock using arduino which can detect the pattern of your knocks at the door and will only open the lock if the knocking pattern matches with the correct pattern.

The aim is to control a door lock without keys but using a smart phone instead. This is a simple project made with arduino uno r3. First of all connect the fingerprint sensor to the arduino uno. The code for password based door lock security system using arduino keypad is given below.

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. Just thought of making a password based door lock system in which you can enter the password via the keypad. The communication medium will be the internet wifi module esp8266.

We don t use keypad or complicated mechanical elements and these are advantages of this system. For the proper working demo check the video at the end. Similarly for unlocking we ll write low value to d0 and high value to d3. We ll discuss the arduino code and circuit design later in this tutorial.

Make sure you get a fingerprint sensor that works with the arduino through the serial communication. I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. The simply compile it then finally upload it to the atmega328 microcontroller.
