🔐Automatic Barrier Opener with RFID Card

Описание: In this project, I built an Automatic Barrier Opener using RFID Card and Arduino 🔐🚪. This smart security system allows you to unlock and open a barrier just by tapping an RFID card—no keys needed!

The system uses an RFID-RC522 module to read the card and an SG90 servo motor to control the barrier movement. When a valid card is detected, the barrier opens automatically and closes after a few seconds.

This project is perfect for beginners and useful for home security, parking systems, and smart gates.

Components Used:

Arduino Uno
RFID-RC522 Module
SG90 Servo Motor
RFID Card/Tag
Jumper Wires
Power Supply

Features:

Contactless entry system
Automatic barrier opening & closing
Secure access with RFID cards
Easy to build and modify

Future Upgrades Ideas:

Add LCD/OLED display to show access status
Add buzzer for sound alert
Connect with WiFi (ESP8266) for remote control
Store multiple RFID cards
