Smart Door Lock System Project Using Arduino

First of all connect the fingerprint sensor to the arduino uno.

Smart door lock system project using arduino.

You can simply copy paste the code using arduino ide. The simply compile it then finally upload it to the atmega328 microcontroller. Download the library for keypad h from below. This is a simple project made with the arduino uno r3.

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. The aim is to control a door lock without keys and using a smartphone to accomplish this. 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.

It was an interesting project which required beginner s level skill in programming and very easy to connect circuit. This will signal the arduino to unlock the door. I have already posted an tutorial about the same project with bluetooth module you can refer it for any clarifications. 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.

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. Similarly for unlocking we ll write low value to d0 and high value to d3. For locking we use the digitalmultiwrite method from library to write high value to d0 and low value to d3.

Probably you have seen smart locks for doors that have a keypad or use a fingerprint to set the door lock or unlock. We don t use keypad or complicated mechanical elements and these are advantages of this system. This is a simple project made with arduino uno r3. Just thought of making a password based door lock system in which you can enter the password via the keypad.

This will signal the arduino to lock the door. The code for password based door lock security system using arduino keypad is given below. We ll discuss the arduino code and circuit design later in this tutorial.
