4.2DISCRIPTION OF CIRCUIT DIAGRAM:-

This project mainly use GSM Module and Arduino.When GSM

module is connect to Arduino it required MAX 232.In GSM module main

pin are TXD, RXD, GND, VCC.

TXD: Transmit data

RXD: Receive data

GND: connect with Ground

VCC: power supply

MAX232 IC is 16 pin IC that is converts signal from an RS232

serial port to signals suitable for use in TTL compatible digital logic circuit.

It use RS 232 port is a driver IC to convert the AT command TTL logic to

the RS 232 logic. Much device today work on RS 232 logic such as, GSM

modem. So, in order to communicate with such devices we have to bring the

logic levels to the 232 logic.

Arduino micro-controller is 32 pin IC. Where 6 pin is analog and

12 pin is digital. Digital pin is used in our project is connect the LCD and

L293D. The Arduino works on TTL logic .So to convert the TTL logic to RS

232 logic we use the 4 capacitors connected to the RS232 IC. These Here in

our project we have One RS232 through which we can connect of serial

Devices .So in our project we have Devices that work on serial GSM

modem.We connect the Arduino pin TXD is connected to RS232 IC pin

R2OUT pin .TXD is transmit the data and pin R2out receive the data.

Arduino pin RXD is connected to RS232 IC pin T2IN pin .RXD is the

receive data and T2IN pin transmit the data to the RXD pin of RS 232 as

shown and the GSM to the TXD pin of RS 232 .


29/61

LCD is use to display. It is connected to the digital pin of

Arduino.LCD has 4 data lines and 3 control lines .The 4 data lines of LCD

(pin 11 to pin 14 of LCD) are connected to Aurdino the control lines are

LCD RS, LCD R/W, and LCD E. In this we are connecting only 2 lines, via,

LCD E and LCD RS.

The LCD RD/WR is grounded, since we only write into the LCD

and never read from LCD. These 2 lines are connected to the pin1 VCC pin

16 is connected to the GND. The LCD RS is for selecting the data or the

code register .The LCDR/W is for choosing between reading and writing on

LCD.

Although only used 1 motor, it is possible to use 4 motors on a

single L293D chip. Remember that if you use 2 motors, the power sourcewill be the same voltage but the current needed will be doubled .

The L293D is a monolithic integrated, high voltage, high

current.,the L293D chip is also known as a type of H-Bridge. The H-Bridge

is typically an electrical circuit that enables a voltage to be applied across a

load in either direction to an output, e.g. Motor.

Motor works by having 4 elements in the circuit commonly

known as corners: high side left, high side right, low side right, and low side

left. By using combinations of these you are able to start, stop and reverse

the current.

Arduino power supply or since motor power supply is only 6V

Im going to use this if the motor supply was higher I would consider using a

transistor or voltage regulator. The only thing to remember is that the

grounding connection must be shared/ common for both supplies.

Generally, DC motors require a lot more current than the

Arduino board .It need a few capacitors in this circuit to smooth out the

power load to the motors .

4.4 RESISTER

FIG. 4.4.4 RESISTER

There is always some resistance in every circuit.

A circuit is always made up of some wire, so there will be some resistance there.

Even thebattery has parts that offer resistance to the flow of

Electrons.

The only circuits that come near to zero resistance are

Superconductors.

This resistance that is from the parts of the circuit itself (especially

the battery) is called internal resistance.

This internal resistance is usually drawn into a circuit

diagram (schematic) as shown in Figure 1. Notice the squiggly line just before the positive terminal of

the battery? Thats to show the internal resistance of the

Circuit.

That symbol, drawn any other place in the circuit, represents an actual

resistorplaced in the


41/61

41

Circuit.

A resistor is a device found in circuits that has a certain amount of resistance.

4.5 CAPACITOR:-

FIG. 4.4.5 CAPACITOR

An electric circuit element used to store charge temporarily, consisting in generalof two metallic plates separated and insulated from each other by a dielectric. Also

called condenser.

A Capacitor is charged when electrons from a power source ,such as a battery

,flow to one of the two plates. Because the electrons can not pass through the

insulating layer, they build up on the first plate, giving it a negative charge.

Electrons on the other plate are attracted to the positive terminal of the battery

,causing that plate to become positively charged.

4.6 DC MOTOR

FIG.4.4.6 DC MOTOR

A DC motor relies on the fact that like magnet poles repels and unlike magnetic

poles attracts each other. A coil of wire with a current running through it generates

an electromagnetic field aligned with the center of the coil. By switching thecurrent on or off in a coil its magnetic field can be switched on or off or by

switching the direction of the current in the coil the direction of the generated

magnetic field can be switched 180.

A simpleDC motortypically has a stationary set of magnets in the stator and an

armature with a series of two or more windings of wire wrapped in insulated stack

slots around iron pole pieces (called stack teeth) with the ends of the wires

terminating on a commentator Workings of a brushed electric motor with a two-pole rotor (armature) and permanent magnet stator. "N" and "S" designate

polarities on the inside faces of the magnet the outside faces have opposite

polarities. The +and -signs show where the DC current is applied to the

commutator which supplies current to the armature coil.

4.7 LCD:-

Short for liquid crystal display, a type of display used in digital watches and

many portable computer.LCD displays utilize two sheets of polarizing

material with a liquid crystal solution between them.

An electric current passed through the liquid causes the crystals to align sothat light cannot pass through them. Each crystal, therefore, is like a shutter,

either allowing light to pass through or blocking the light.

FIG.4.4.7 LCD

LCD (Liquid Crystal Display) screen is an electronic display module and find a

wide range of applications. A 16x2 LCD display is very basic module and is very

commonly used in various devices and circuits. These modules are preferred over

seven segments and other multi segment LEDs.

A 16x2 LCDmeans it can display 16 characters per line and there are 2 such

lines. In this LCD each character is displayed in 5x7 pixel matrix. This LCD has

two registers, namely, Command and Data. The command register stores thecommand instructions given to the LCD.

4.8 CRYSTAL OSCILLATOR

FIG.4.4.8 CRYSTAL OSCILLATOR

A crystal oscillator is anelectronic oscillator circuit that uses the mechanical

resonance of a vibratingcrystal ofpiezoelectric material to create an electrical

signal with a very precisefrequency.This frequency is commonly used to keep

track of time (as inquartz wristwatches), to provide a stableclock signal for

integrated, and to stabilize frequencies forradio transmitters andreceivers.The

most common type of piezoelectric resonator used is thequartz crystal, but otherpiezoelectric materials including poly crystalline ceramics are used in similar

circuits.

9 IC .MAX232

FIG.4.4.9 MAX232

The MAX232 is an IC, first created in 1987 byMaxim Integrated Products,that

converts signals from anRS-232 serial port to signals suitable for use inTTL

compatible digital logic circuits. The MAX232 is a dual driver/receiver and

typically converts the RX, TX, CTS and RTS signals.

The drivers provide RS-232 voltage level outputs (approx. 7.5V)from a single +

5 V supply via on-chipcharge pumps and external capacitors. This makes it useful

for implementing RS-232 in devices that otherwise do not need any voltagesoutside the 0 V to + 5 V range, aspower supply design does not need to be made

more complicated just for driving the RS-232 in this case.

The receivers reduce RS-232 inputs (which may be as high as 25 V), to standard

5 VTTL levels. These receivers have a typical threshold of 1.3 V, and a typical

hysteresis of 0.5 V

CONCLUSION

In this project, the method of Vehicle security systems used to secure the theft

vehicle by using GSM technology. This system puts into the sleeping mode vehiclehandled by the owner or authorized persons; otherwise goes to active mode. The

mode of operations changed by persons or remotely. When the theft identified, the

responsible people send SMS to the micro controller, then issue the control signals

to stop the engine motor. After that all the doors locked. To open the doors or to

restart the engine authorized person needs to enter the passwords. In this method,

easily track the vehicle place and doors locked.

Future work:-

Our project is provide more security of vehicle. This project brings technology

effectively in security and surveillance segment of industry.

This device is implemented to the vehicle will reduced the theft .

In this project we can control the engine, light, door lock etc through SMS. Infuture we use the eye lock and finger print system and give the more security for

vehicle.

In future we can add the GPS module. It provides more security and exact locationfor the vehicle. Same as small change in program and hard ware and it is use in

house hold application as well as industry; bank, etc control the system andprovide more security.

It can be used as home automation substituted in house hold application. This

project itself can be modified to achieve a complete home automationsystem .Which will then create a plat from for user to interface with the hose hold.
