The ROBODIUM Access Pro Kit is a complete RFID-based smart door security system designed for beginners, students, and DIY hobbyists. Using the RC522 RFID module and a high-quality solenoid lock, this kit allows you to build a secure digital access control system similar to office ID-card entry systems.
With Arduino UNO as the controller, the door unlocks only when an authorized RFID card or tag is scanned. The included 1-channel relay drives the solenoid lock safely, while the 16x2 LCD display shows access status in real time.
Perfect for school projects, engineering mini-projects, home/office automation, and IoT security experiments.
