Rfid Based Door Lock System Using Arduino Uno

This rfid based access control system is built around arduino uno board rfid reader module solenoid lock and a few other components.

Rfid based door lock system using arduino uno.

The rfid tag consist of integrated circuit and an antenna integrated circuit is for the storage of the data and an antenna is for transmitting the data to the rfid reader module. The necessity of power supply for rfid readers varies from one product to another. 3 x led s red green blue 3 x 220 ohm resistors. 6 to 12v power source i have used 3 x 18650 cells circuit diagram and explanation.

The components you are going to require for rfid based access control system using arduino are as follows. Working of arduino based rfid door lock the rfid system consists of two components. Arduino uno or any other arduino. In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matri.

Rfid is a non contact automatic identification technology that uses radio signals to identify track sort and detect a variety of objects including people vehicles goods and assets without the need for direct contact or line of sight contact as found. When we see sophisticated door management system s the price tag struck immediately along with the utility of course. An rfid tag and a reader. Rfid stands for radio frequency identification and it s a non contact technology that s broadly used in many areas such as personnel tracking access.

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. There are many rfid readers are available in the market with 5v 9v and 12v. The connection with the arduino uno board is very simple. This is a simple arduino project.

Since the display can also work at 3 3v we connect the vcc from both modules to the breadboards positive rail. In this tutorial we are going to learn how the mfrc255 rfid reader works and how it can be interfaced with arduino in a number of projects like the arduino based rfid door lock system. But here a 12v rfid reader is used for an. On scanning the wrong tag or on entering the wrong password the system will deny access.

Arduino uno rfid based automatic door lock system using an arduino. At first let s connect the power of both the reader and the display. To open the door the user will have to first scan the right tag and then he will have to enter the correct password. Interfacing of rfid with arduino can be done by the following steps.
