This paper presents a design and implementation of automated car parking system by using RFID and passcode technologies. In this system, a parking tower with three floors and two slots per floor on either sides of the central lift was implemented. The control of entry-point and exit-point from the parking-lots is one of the applications of Radio Frequency Identification (RFID) technology which leads to the high reliability and security issues. RFID is a wireless technology to identify and track tags attached to objects via radio waves. The parking lots have an elevator to carry vehicles to different floors according to the vacancies that are collected by using an RFID system and are updated periodically into the database. This project is designed with RFID system, stepper motor for elevator, servo motor for turning the pallet to desired position, and DC motor for moving and placing the vehicles toward the specified slot of parking. This project will help to minimize the car parking area companies and apartments. And also it will help to reduce the manual work and save time.
