Paid Car Parking Project Based On RFID
The project is a car authorizing system where the system can only allow a car entry when a valid RFID card id swiped by the car owner. The system also had paid parking facility where the amount of parking gets deducted automatically whenever the card is swiped and the available number of car parking are displayed on a seven segment display.
The project requires a sensing circuits and a microcontroller to monitor the entry and exits of cars.
The entry and exit is operated by an H-bridge arrangement. This arrangement operates the motors that enable exit and entry by opening and closing the door clockwise and anticlockwise. Whenever the card is swiped a buzzer sound comes. With every entry the available number of parking gets reduced by one and with every exit it gets reduced by one and is displayed on seven segment display.
