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.
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.
This will signal the arduino to lock the door.
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.
We ll discuss the arduino code and circuit design later in this tutorial.
For the proper working demo check the video at the end.
Make sure you get a fingerprint sensor that works with the arduino through the serial communication.
The aim is to control a door lock without keys and using a smartphone to accomplish this.
Smart bt door lock simple arduino project showcase by arun.
The code for password based door lock security system using arduino keypad is given below.
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.
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 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.
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.
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.
Download the library for keypad h from below.
You can simply copy paste the code using arduino ide.
First of all connect the fingerprint sensor to the arduino uno.
Probably you have seen smart locks for doors that have a keypad or use a fingerprint to set the door lock or unlock.
This will signal the arduino to unlock the door.
