Abstract
This is an IoT-enabled RFID-based door locking gadget. This door lock system will know how long the door is open and in this door lock system, only those people who register will be able to enter using their card. It uses a servo motor that operates with the help of Arduino. The Arduino board runs with complete programming that is stored inside it. By using this gadget, an owner can track his office and the place where he wants to let the specific people in. It is also very secure. RFID Module, LCD Display Red and Green and Yellow LED Light and Buzzer have also been used in this door lock system. When the door is locked, the yellow LED will be on and when the door lock is open, the green led light will turn on. The Red LED work will alert you that your card is wrong.
Highlights
This gadget is designed with the help of an Arduino using a servo motor that pushes the gear forward and back
In simple language, when a card is scanned, the condition given in the programming matches, the command given in that condition becomes active, such that when the correct card is scanned, the open condition will match, in which the servo motor will rotate 90 degrees and The green light will be on and the buzzer will beep for 500 microseconds and the door lock will be open but when an unregistered card is scanned the condition of the wrong card will match which will beep twice for 500 microseconds and the red light will be on for 1 second
By using Arduino [6] automatic RFID-based access control system was designed this system represents a combination of RFID system and order no to achieve a particular task
Summary
This gadget is designed with the help of an Arduino using a servo motor that pushes the gear forward and back. When we scan our register card, there is a loop start of store programming in which the servo motor rotates 90 degrees, the gear mechanism in it works, which locks and opens the lock. In simple language, when a card is scanned, the condition given in the programming matches, the command given in that condition becomes active, such that when the correct card is scanned, the open condition will match, in which the servo motor will rotate 90 degrees and The green light will be on and the buzzer will beep for 500 microseconds and the door lock will be open but when an unregistered card is scanned the condition of the wrong card will match which will beep twice for 500 microseconds and the red light will be on for 1 second.
