You have seen rfid door lock mechanism in some hotels and other places where you don t need a key to unlock the room.
Rfid door lock using arduino uno.
Mosi pin goes to digital pin 11.
Unlocks a door controls a relay actually using a rc522 rfid reader with spi interface on your arduino.
The rfid reader module uses the spi interface in order to communicate with arduino.
With this simple tutorial we can apply this application to control the huge things in our life.
On scanning the wrong tag or on entering the wrong password the system will deny access.
In this case we will then use a relay so we can make it work too we are using the plunger as a lock so here is the connections for it.
As we are using a plunger it requires 9 volts to work and as we all know an arduino uno only has max 5 volts.
The goal is to open a door by using a specific tag that functions as an access badge.
Easy user interface just one rfid tag needed whether delete or add tags to memory.
Hey friends in this video i will show you how to make rfid lock system visit my website to download codes and circuit diagrams https www viralsciencecrea.
Irq pin stays unconnected.
Rfid door lock with arduino.
So we are going to use the hardware spi pins of the arduino uno.
You define a master card which acts as a programmer then you can able to choose card holders who can able to unlock the door or not.
Rfid and keypad based door lock using arduino.
Please try again later.
In this post on arduino tutorial for beginners this topic about how to use module rfid rc522 with arduino uno r3.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
Rst pin goes to digital pin 9.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
In this post you are going to learn about how to build an rfid and keypad based door lock using arduino.
This is a simple project made with arduino uno r3.
An error occurred while retrieving sharing information.
Smart bt door lock simple arduino project showcase by arun.
The i2c pins on arduino uno and arduino nano are a4 a5.
The aim is to control a door lock without keys but using a smart phone instead.
Project this project guide will detail the steps to create an rfid radio frequency identification door lock system using an arduino mega 2560.
Arduino rfid door lock hardware project setup.
You are given a card and you just need to put it in front of a rfid reader box and the lock gets unlocked with a beep and a blink of led.
The 4x4 keypad has 8 connections but we don t require the last column of keypad.
To open the door the user will have to first scan the right tag and then he will have to enter the correct password.
