This project involves developing an autonomous vehicle designed to navigate its surroundings and avoid obstacles using an ultrasonic sensor. The vehicle is powered by Arduino, utilizes the SR04 library for distance measurement, and is programmed in the Arduino language. It uses sensors and motors to detect obstacles and respond by moving forward, turning, or stopping based on set thresholds.

Key components include an Arduino Uno, ultrasonic sensors, motors, and a servo motor. Despite challenges, such as motor limitations, the project successfully demonstrated the potential of sensors and programming in creating autonomous systems.

This work highlights applications in improving traffic flow, reducing accidents, and inspiring further research in autonomous technologies.

This project focuses on enhancing safety and accessibility in modern homes through the integration of embedded sensors. The system features four key sensors:

• Temperature Sensor: Monitors room temperature in real-time and adjusts fan or air conditioning speed.
• Gas Sensor: Detects flammable gases, such as methane, and alerts the user in case of a leak.
• Water Sensor: Monitors water levels in tanks, detects rain, and signals the user to close openings to prevent leaks.
• Moisture Sensor: Tracks soil moisture levels and notifies the user when plants need watering.

The system consolidates all sensor data into a single LCD display for easy access. Additionally, it includes a hex keypad-based locking mechanism for enhanced security.

This prototype demonstrates the potential of embedded systems to improve home safety, resource management, and user convenience. Future improvements could include additional sensors and remote monitoring capabilities via mobile applications.
