Smart Door Lock System Project Using Arduino

The communication medium will be the internet wifi module esp8266.

Smart door lock system project using arduino.

The simply compile it then finally upload it to the atmega328 microcontroller. First of all connect the fingerprint sensor to the arduino uno. 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. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit.

For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3. Smart bt door lock simple arduino project showcase by arun. The aim is to control a door lock without keys but using a smart phone instead. The code for password based door lock security system using arduino keypad is given below.

You can simply copy paste the code using arduino ide. Probably you have seen smart locks for doors that have a keypad or use a fingerprint to set the door lock or unlock. For the proper working demo check the video at the end. The aim is to control a door lock without keys and using a smartphone to accomplish this.

We don t use keypad or complicated mechanical elements and these are advantages of this system. 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. This will signal the arduino to unlock the door. This is a simple project made with the arduino uno r3.

We ll discuss the arduino code and circuit design later in this tutorial. Similarly for unlocking we ll write low value to d0 and high value to d3. I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. This is a simple project made with arduino uno r3.

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. Make sure you get a fingerprint sensor that works with the arduino through the serial communication. This will signal the arduino to lock the door.
