Smart Door Lock System Project Using Arduino

The aim is to control a door lock without keys but using a smart phone instead.

Smart door lock system project using arduino.

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. Just thought of making a password based door lock system in which you can enter the password via the keypad. The code for password based door lock security system using arduino keypad is given below. Download the library for keypad h from below.

The simply compile it then finally upload it to the atmega328 microcontroller. Similarly for unlocking we ll write low value to d0 and high value to d3. This is a simple project made with arduino uno r3. First of all connect the fingerprint sensor to the arduino uno.

Make sure you get a fingerprint sensor that works with the arduino through the serial communication. We don t use keypad or complicated mechanical elements and these are advantages of this system. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. For the proper working demo check the video at the end.

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. You can simply copy paste the code using arduino ide. More about einzigartig arun this is a simple project made with the arduino uno r3 the aim is to control a door lock without keys and using a smart phone to accomplish this the communication medium will be the internet wifi module esp8266.

I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. The communication medium will be the internet wifi module esp8266. 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. Smart bt door lock simple arduino project showcase by arun.

Probably you have seen smart locks for doors that have a keypad or use a fingerprint to set the door lock or unlock. We ll discuss the arduino code and circuit design later in this tutorial. This is a simple project made with the arduino uno r3.
