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 with sufficient balance. 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 consists of IR sensors 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. For demonstration purposes the system has used RFID cards to simulate real time user cards. Whenever the card is swiped a buzzer beeps. 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. The system stops allowing new cars to enter if all parking slots are full. Also a users card can be recharged using a recharge button.
