The circuit diagram of arduino and rfid based door access system is shown in figure 1.
Rfid multiple door lock system using arduino.
When we see sophisticated door management system s the price tag struck immediately along with the utility of course.
Arduino rfid door lock circuit diagram.
Most arduino pre flashed atmega 168 chips come with the default blink program pre installed.
The circuit basically consist of arduino uno central control unit rfid receiver module rfid tag solenoid lock and few other electronics components like resistor capacitors diodes transistors etc.
Em 18 rfid reader operates at 125 khz and it comes with an on chip antenna and it can be powered with 5v power supply.
Each rfid card has a unique id embedded in it and a rfid reader is used to read the rfid card no.
In countries like india such automatic systems are not cheap by any yardstick.
Rfid uses electromagnetic fields to identify and track tags attached to an object.
The rfid lock box combines arduino rfid and a solenoid to make your very own personal safe.
If the wrong tag is scanned the door will stay closed and set off a buzzer.
To drive the solenoid lock you would need a power source that can give 12v 500ma.
Connections between arduino and rfid are given in the table below.
The goal is to open a door by using a specific tag that functions as an access badge.
Rfid stands for radio frequency identification.
It doesn t use any power in a locked state.
These tags contain electronic stored information.
Circuit diagram for solenoid door lock using arduino is given below.
So we decided to test a simple and cheap prototype to see if such a robust system could be developed using the tool of our choice arduino uno.
In this project tutorial you will use the multiple mfrc522 to control a solenoid lock and three leds.
The arduino based rfiddoor lock system is secure and responsive as compared to other systems.
The positive pin of the buzzer is connected to digital pin 4 of arduino and the gnd pin is connected to the ground pin of arduino.
The rfid module works as sensor.
I just finished installing an rfid door lock system using an rdm6300 rfid reader an arduino and an electric strike plate.
For the most part i followed this guide from practical arduino.
When the power is disconnected the slug moves outside and locks the door.
Program a code and uploadit to arduino just like a plug and play device.
It provides serial output along with weigand output.
Hii friends today i ll show you how to make rfid door lock system using arduino nano.
Withthe use of arduino it becomes much easy to design.
The first step to building a rfid door lock with a basic arduino is to bread board out a basic working arduino.
The mfrc522 uses radio frequence identification rfid.
