Smart Door Lock System Project Using Arduino

Probably you have seen smart locks for doors that have a keypad or use a fingerprint to set the door lock or unlock.

Smart door lock system project using arduino.

This is a simple project made with the arduino uno r3. We don t use keypad or complicated mechanical elements and these are advantages of this system. 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. The simply compile it then finally upload it to the atmega328 microcontroller.

For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3. The communication medium will be the internet wifi module esp8266. 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. 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.

The aim is to control a door lock without keys but using a smart phone instead. Smart bt door lock simple arduino project showcase by arun. Similarly for unlocking we ll write low value to d0 and high value to d3. 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. This will signal the arduino to unlock the door. It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. 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. You can simply copy paste the code using arduino ide. For the proper working demo check the video at the end. First of all connect the fingerprint sensor to the arduino uno.

We ll discuss the arduino code and circuit design later in this tutorial. Just thought of making a password based door lock system in which you can enter the password via the keypad. This is a simple project made with arduino uno r3.
