This document describes a project to design and build a prototype automated parking lot system using an Arduino board. The objectives are to control the system for automated parking and learn how to program Arduino. The system will use sensors to track the number of occupied and unoccupied spaces, raise gates to allow entry and exit, and track parking times. An Arduino Uno microcontroller, sensors, servo motor, 7-segment display and other components will be used to control the gates and display parking information based on sensor inputs. The code will be programmed using the Arduino IDE and uploaded to the microcontroller to operate the system.

- 2. Project Objectives: To design and build up a prototypeof an automated car park system. To learn how to control the prototype system for automated parking. To acknowledge how to program Arduino and make it work on any system. Special Key points of this project: Developing this project will give one an idea to either how to implement a relatively complex project or give one enough hands on experience to apply for an entry level job on application of Microcontrollers with full confidence. TheoreticalConcept: Arduino is an open source prototyping platform based on easy to use hardware and software. Arduino boards are able to read inputs-light on a sensor, a finger on a button or a Twitter message, and turn it into an output activating a motor. In this project, we will develop a microcontroller or an Arduino board based system which keeps track of the number of cars parked (9 being the max number), shows the number of slots which are unoccupied. It automatically raises the gate arm to allow cars into the parking lot or leave it. Other functions include keeping track of how much time a car has been parked and the time when a driver leaves the parking lot. As an ending process, when a car tries to exit and the exit arm gate is raised, one unit is added to the total number of vacant cars in the parking lot. There is only a difference between the microcontroller based version and the Arduino one: in the Arduino version, a RFID module is used to record the entrance of a car into the parking lot as opposed to microcontroller based which detects the parking

- 4. Manual of the Project: The purposeof this manual is to design and implement a Microcontroller based Parking system. This is intended for those who are familiar with the basic instructions of any typical microcontroller and programming language. In this case, we are going to prepare a control program for an AVR microcontroller and Arduino board to controla car parking system. Working Procedures: At first we compiled the source code to the Arduino’sIDE (Integrated Development Environment) and then uploaded it in the micro-controller of the Arduino. Then we have connected the seven pins of 7 segment display with the Arduino’s0 to 6 pins through seven 470 ohm resistors and the VCC pin of the display has been connected through a 470 ohm resistor with Arduino’s VCC pin. To control the intensity of the display, the dot point (dp) has been connected with Arduino’s pin no 11. After that we have connected the brown wire from the servo motor to the ground, the red wire to the VCC (+5V) and the orange wire to the Arduino’s pin no 12 as signal. To pass the signal to the Arduino we have used aluminum foil as sensor switch pad in enter and exit point of our parking lot. Then Arduino’s pin no 8 & 9 have been used as enter and exit and there is a common ground for them. A piece of plastic is used as barrier which is connected to the servo motor. When the sensor in the enter point is on, the barrier opens up and after 2000 micro seconds it closes down. At the time of closing the barrier, the number of vacancy decreases one by one. When a car left the parking lot, the sensor at the exit point becomes active and eventually the number of vacancy increases. The most important part is that when the vacancy is full (i.e. display shows 0), the barrier doesn’t open up and then no car is allowed to enter into the parking lot.

- 6. Discussions: The cars will be entering into the lot and the lot is filed. When the lot is filled, the vacant spaces are zero and no car is allowed to enter. Now, the power is gone, and comes back. Then the seven segment display showsthe maximum count, though the lot is filled, means the Arduino is allowing the others cars to enter the lot. Now, theanother one, the car is ready to enter the lot. The car approaches the gate and gate opens up. Now the driver is in urgency and left. Though the car has not entered the lot, the count is decremented. Car reaches the gate, aluminum foil comes in contactand gate opens. Though the gate is open, the driver doesn’tenter, means when the aluminum foils are continue to remain in contact then the count keeps on decrements and after reaching zero the gate closes. At the time of entering two consecutive cars, there is an overcrowding situation. There is a prohibition of entering and leaving two cars at a time.
