This door lock will only open the door when the user scans the right fingerprint that is recorded on the system but the door will remained close upon entering the wrong fingerprint.
How to make an arduino door lock.
Here we will make a smart rfid door lock by using arduino and ultrasonic sensor.
In this tutorial i m going to show you how to build a door lock that uses a fingerprint sensor and an arduino uno.
To connect the servo motor with the arduino use digital pin d9 of arduino to output the pwm pin of the servo motor.
I built a simple circuit with a basic atmega 168 arduino chi.
For connecting the keypad with the arduino we are using digital pins d1 to d7.
This is a really easy rfid door lock mechanism which is based on the arduino uno and the rc522 rfid sensor which allows you to use rfid tags or cards to lock and unlock a door drawer or cupboard.
In this tutorial you will learn how to create a password protected lock with a keypad relay tm1637 display and an arduino uno board.
I hope you guys enjoy learning this project.
Arduino rfid sensor rc522 servo motor.
To connect it to the arduino we will require a relay and a battery.
Updated 8 9 2010 i wanted to make an easy and secure way to enter my garage.
The components required for this project are as follows.
First of all we will make a connection to the 4 3 keypad.
Arduino keyless door lock system with keypad and lcd 0.
In this project we are going to make a keyless door lock system which uses a 4x4 keypad to enter the keys and a dc lock to open or close the door.
When i show my college id it will open the door.
In this tutorial we will see how to make rfid door lock.
And you can see when i show wrong card or wrong key chain tag it will make sound.
We will use a user input from the keypad to determine of the correct code is entered.
A 16x2 lcd will be used for display.
How to make a arduino door lock make a arduino door lock system with keypad using and servo motor arduino door lock system with password base how to make a d.
For closing the door we have to again show college id.
So let s get started.
Arduino rfid door lock.
Connect all seven pins of the keypad to analog pins d1 d7 of arduino.
Connect the signal pin of the relay to pin 10 on the arduino and the lock s vcc and gnd to 5v and gnd on the arduino.
For this you will need.
The lock operates on a voltage from 7 to 12v so we cannot directly connect it to the arduino.
You can load as many rfid tags as you d like onto the arduino and add or remove tags to provide more or fewer people with access.
