This document describes an automatic car parking system. It discusses the basic components of the system including a microcontroller, sensors, motor driver, DC motor and LCD display. Infrared sensors are used to detect when a car enters or exits and an RFID reader is used to detect vacant spaces. When a sensor detects a car, the microcontroller activates the motor driver and DC motor to rotate the motor in the appropriate direction to open or close the gate. The system allows for automated parking without human assistance and saves space compared to traditional parking methods.

4. TRADTIONAL CAR PARKING4

5. System overview
 Parking system is based around micro controller and
sensors
 This process is quick and efficient.

6. POWER SUPPLY6

7.  Power supply is the circuit from which we get a desired dc
voltage to run the other circuits.
 The voltage we get from the main line is 230V AC but the other
components of our circuit require 5V DC.
 Hence a step-down transformer is used to get 12V AC which is
later converted to 12V DC using a rectifier.
 The output of rectifier still contains some ripples even though it is
a DC signal due to which it is called as Pulsating DC.
 The 12V DC is rated down to 5V using a positive voltage regulator
chip 7805. Thus a fixed DC voltage of 5V is obtained.

8. MICROCONTROLLER
 A microcontroller (sometimes abbreviated µC or MCU) is a
small computer on a single integrated circuit containing a
processor core, memory, and programmable i/o peripherals.
 Microcontrollers are designed for embedded applications, in
contrast to the microprocessors used in PCs or other general
purpose applications.

11. LCD11

12.  The display used here is 16x2 LCD (Liquid Crystal Display);
this means 16 characters per line by 2 lines.
 A very popular standard exists which allows us to
communicate with the vast majority of LCDs regardless of
their manufacturer.
 The 44780 standard requires 3 control lines as well as either
4 or 8 I/O lines for the data bus. Here we are using 8-bit
mode of LCD, i.e., using 8-bit data bus.

13. SENSORS
 A sensor, as the name suggests, is used to sense any type
of disturbances
 A sensor can give analog as well as digital value.
 A sensor also called a detector is a device which receives
and responds to a signal.
 A sensor's sensitivity indicates how much the sensor's
output changes when the measured quantity changes.

14. IR SENSORS14

15.  IR stands for “Infra Red”.
 IR Sensor is a sensor that sends and detects IR
Radiation/Signals.
 Infrared radiation is the portion of electromagnetic spectrum
having wavelengths longer than visible light wavelengths, but
smaller than microwaves, i.e., the region roughly from 0.75µm
to 1000 µm is the infrared region.
 Infrared waves are invisible to human eyes.
 These are of 3 types near infrared, mid infrared, far infrared

17. Motor driver17

18. Working
 To drive a motor we need some drivers which can amplify the 5v
voltage to 12v.
 These days many IC manufacturers have H‐bridge motor driver
available in the market like L293D is most used H‐ Bridge driver IC.
 H‐bridge can also be made with the help of transistors and MOSFETs
etc.
 This IC is used to control the motor in forward, backward, left and right
direction.

19. DC MOTOR19

20. Hardware working
 TheATmega16is the brain of this whole hardware.
 It reads the input signals and start sending the stepping sequences to the
motor.
 When the input beam of S1 is blocked motor start rotating in clockwise
direction.
 S1 indicates that a car has come.
 The S2 sensor is used as the gate open limit sensor
 when S2=ON it means gate is completely opened.
 motor start rotating in counter clockwise direction, closing now.
 Finally, when S3=ON it indicates that gate is completely closed now.
 RFID card gives the signal that space is vacant for the car parking.

22. ADVANTAGES
 Over 5,000 parking systems in use worldwide.
 Less Pollution
 Security from Theft and Car Damages
 Save you space, time & money
 Simple structure, simple operation
 Speedy system, moves smoothly, not noisy.
 It can be constructed and implemented in residential
areas.
 Present smart card offers very low read range
22

23. LIMITATIONS
 Parking lots also tend to be subject to contamination.
 concentrated spots of pollutants such as motor oil.
 preferred shaded parking spaces in the summer.
 planting trees because of the extra cost of cleaning
the parking lot .

24. CONCLUSION
 Important factor in traffic areas
 Automated without human being
 motor plays a vital role
 Display is used at every floor
 Sensors are used for sensing the car.
