Project Overview
This project is a smart vehicle interior security and control system using Arduino and Proteus developed for the Programming Laboratory II course at Kocaeli University. It aims to replicate the safety and comfort features found in modern cars on a microcontroller-based platform.
Features:
Engine Start and Seatbelt Check:
The engine cannot start unless the seatbelt is fastened.
Buzzer and red LED activate if the seatbelt is unfastened.
Informative messages are displayed on the LCD.
Temperature Monitoring and Automatic Air Conditioning:
When the interior temperature exceeds 25°C, the air conditioning (simulated by a DC motor) is automatically activated.
Real-time temperature readings are shown on the LCD.
Automatic Headlight Control:
Lights (blue LED) turn on automatically in low light conditions detected by an LDR sensor.
LCD updates with headlight status messages.
Fuel Level Monitoring:
Simulated using a potentiometer.
If fuel level drops below 10%, a yellow LED warns the driver.
Critical warnings at fuel levels below 5% and complete engine shutdown at 0%.
Door Status Monitoring:
If the door is open, the engine will not start.
Pink LED and LCD alerts notify the driver of the open door.

Setup and Installation
Clone this repository
Open the .ino file in the Arduino IDE.
Upload the code to the Arduino Mega 2560 board or launch Proje 2.pdsprj in proteus.
Link the .hex file to the board and start the simulation.
Usage
Press the Motor Start button to attempt to start the engine.
Fasten the seatbelt to allow engine start.
Monitor temperature, light, fuel, and door status via the LCD screen and indicator LEDs.
