Introduction
The microcontroller registers the action and sends a signal to the GSM, which will coordinate with the company's unit and the police. The microcontroller will also send a signal to the relay, which will turn off the car's ignition and stop the car.
Objectives
Methodology
Gears consist of an electric motor and gears that form a kinematic chain - the fundamental component of the gear ratio. The input pins are connected to any digital circuit or microcontroller to control the speed and direction of the motor. And in the old security system, if the car is stolen, it is out of the owner's control.
This will save the lives of the passengers in the car, because it will save them very quickly. Note: Versions of the Arduino software (IDE) prior to 1.0 saved sketches with a .pde extension.

Arduino Nano
The Nano has breadboard and minivan boarding capability with a smaller footprint than either, so users have more board space. It has a layout that works well with the Mini or Basic Stamp (TX, RX, ATN and GND on one end, power and ground on the other). One of the best features of Arduino Nano is that it is easy to use, compact and also small.
The high-performance Microchip Pico Power 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory with read-while-write capability, 1024B EEPROM, 2KB SRAM, 23 general-purpose I/O lines, 32 general-purpose work registers, three flexible timers/counters with compare modes, internal and external interrupts, serial programmable USART, a byte-oriented 2-wire serial interface, SPI serial port, a 6-channel 10-bit A/D converter (8-channel in TQFP and QFN/MLF packages ), programmable watchdog timer with internal oscillator and five software-selectable power saving modes. By executing powerful instructions in a single clock cycle, the device achieves throughput approaching 1 MIPS per MHz, which balances power consumption and processing speed.
Battery
DC Gear Motor
The functional difference between a PNP transistor and an NPN transistor is the correct biasing (polarity) of the junctions during operation. As you can see, the controlling current and the controlled current always go together through the emitter wire, and their electrons always flow against the direction of the arrow of the transistor. The emitter current is the sum of the base and collector currents in accordance with Kirchhoff's current law.
No current flows through the base of the transistor, turning it off as an open switch and preventing current from flowing through the collector. The collector current is primarily limited by the base current, regardless of the amount of voltage available to push it. The correct orientation for inserting the SIM card is usually engraved on the surface of the SIM socket.
The proposed methodology focuses on improving the technology used to improve car safety. If the owner sends e1, then the spy camera clicks images of the intruder. This is the only interactive function of the Help menu: it directly selects the corresponding page in the local copy of the Reference for the function or command under the cursor.
You can view or change the location of the sketchbook location from the Options dialog box. This will insert one or more #include statements at the top of the sketch and compile the library with your sketch. Starting with version 1.0.5 of the IDE, you can import a library from a zip file and use it in an open sketch.
We have successfully developed and implemented a vehicle tracking system that provides feedback on the location of a stolen vehicle using GSM technology. The system is not limited to finding the destination location, but also calculates the distance traveled between two stations.

Transistor
The difference between "P" and "N" doped semiconductors, the functional characteristics of a PN (diode) junction, and the meaning of the terms "reverse biased" and "forward biased". If these concepts are unclear to you, it is best to refer to earlier chapters in this book first. Each layer that makes up the transistor has a specific name, and each layer is provided with a wire contact for connection to a circuit. For any given operating condition, the current directions and voltage polarities for each type of transistor are exactly opposite to each other. Bipolar transistors act as current-controlled current regulators.
In other words, transistors limit the amount of current that passes based on a smaller, controlling current. The main current that is regulated flows from collector to emitter, or from emitter to collector, depending on the type of transistor (PNP or NPN, respectively). Bipolar transistors are called bipolar because the main flow of electrons through them occurs in two types of semiconductor material: P and N, while the main current flows from emitter to collector (or vice versa).
In other words, this main current through the transistor consists of two types of charge carriers: electrons and holes. This is the first and most important rule when using transistors: all currents must flow in the correct direction for the device to act as a current regulator. The small, controlling current is usually simply referred to as the base current because it is the only current that passes through it.
Conversely, the large, controlled current is called the collector current because it is the only current that passes through the collector wire. A base current turns on the transistor like a closed switch and passes a proportional amount of current through the collector.
GSM Module
This module measures just 1 inch², but packs a surprising amount of features into its tiny frame. An external power source such as Li-Po battery or DC-DC buck converters rated at 3.7V 2A would work. If you absolutely have the module in a bad location, pull this pin low for 100ms to perform a hard reset.
GND is the Ground Pin and must be connected to the GND pin on the Arduino. It defaults to high and will pulse low for 120ms when a call is received.

To Build Up the Model
Working Principle
Complete Project Prototype Image
A digital microcontroller device called the Arduino Nano can be configured with the Arduino software IDE. These sketches are written in the text editor and saved with the file extension .ino. The console displays text output from the Arduino software (IDE), including complete error messages and other information.
The Arduino Software (IDE) uses the concept of a sketchbook: a standard place to store your programs (or sketches). The first time you use the Arduino software, a folder for your sketchbook is automatically created. These can be regular Arduino code files (no visible extension), C files (.c extension), C++ files (.cpp), or header files (.h).
On Windows it's probably COM1 or COM2 (for a serial card) or COM4, COM5, COM7 or higher (for a USB card) - to find out, look for USB Serial Device in the Ports section of Windows Device Manager. The Arduino software (IDE) displays a message when the upload is complete or displays an error. When you upload a sketch, you use the Arduino bootloader, a small program that has been loaded onto the microcontroller on your board.
Support for third-party hardware can be added to the hardware directory of your sketch directory. For details on creating packages for third-party hardware, see the Arduino IDE 1.5 Third-Party Hardware Specification. It is user friendly, easily installable, easily accessible and can be used for various purposes.

Proteus
The SPICE mixed-mode simulation was first integrated into Proteus in 1996, and then the microcontroller simulation was introduced into Proteus in 1998. We are still working on the possibility of improving the system to provide SMS feedback to the vehicle owner when an accident occurs takes place. This will help reduce the delay in evacuating accident victims to the hospital and reduce the chances of loss of life.
