Hi Hello Electronics Lovers, in this tutorial i will show you how to secure the main entrance of your Home, office, school or any Restricted area with the help of RFID and Arduino board. Every owner of the house wants to install Home Security System to secure his home as soon as possible, but most of the time they get failed due to low budget and unfortunately they take a step backward from their decision. Now they don’t need to worry because i bring something cool for them, they need average Electronic skills to make this home security system for their houses.
“Theme: At entrance, a User will first show an exact RFID card Tag to access the authorized place otherwise Red Led will start blinking after a couple of unsuccessful attempts”
How RFID Module Works:
RFID stands for- Radio Frequency Identification, RFID uses Electromagnetic waves to read a Unique data of RFID Tag wirelessly. After Successful reading, RFID Module will compare the data of RFID tag with a pre-assigned data added by project admin, if it compares then it will Allow you to do your task otherwise it will not allow you to Access. Every RFID tag has a unique code “18008DC02E7B”, at the beginning you just need to store the data of the authorized RFID tags in your source code one by one before going to the next level, remember only Admin or Project maker can do this JOB. The operatable frequency of RFID is 125KHz and the frequency of RFID module and RFID tag should be same. The distance between Tag and RFID Module should be less than a few centimeter or one inch otherwise it will not read your RFID tag accurately.

Circuit Description of Home Security System by Using RFID and ARDUINO
Circuit diagram of Home Security System by Using RFID and ARDUINO is shown in figure 1. Connection for each and every component is clearly mentioned in the circuit diagram. The heart of this project is Arduino Uno board, RX pin of the Arduino Uno will receive data from the Tx pin of the RFID Module every time when a user wants to Access to an authorized place by showing an RFID tag. If a user has a genuine tag then Arduino will successfully send a HIgh state pulse to pin No 10 that will saturate a transistor to turn on Solenoid lock. In a case where the attempts are unauthorized, the door will remains closed. Additional LED2 start to glow indicating the warning message.
