Figure 2.1: Parking system with Arduino mega2560 board
Some advantages of this parking system compared to the previous one because of using
RFID cards are:
1. Unlike previous project, by using RFID cards, we do not need wiring from 16 slots to
main board controller. Therefore, the using of RFID cards makes a cheaper system.
2. High security against faking because of using RFID card with encryption technology.
( only the operator can read or write time on the cards)
3. This parking system prevents the stealing of cars, because each car needs a card to
exit.
4. The card reader can be restarted, or exchanged, because the primary data (time and
date of entrance) are recorded on cards.
5. There is an internal clock to compute the time and because of using backup battery, if
the system power turns off for a time, it does not have any effect on the system per-
formance.
