Design and Fabrication of an Automatic Breaking System Using Ultrasonic Sensors

Road safety and vehicle automation are critical areas of focus in modern engineering. This project presents the development of a small-scale prototype of an Design and Fabrication of an Automatic Breaking System Using Ultrasonic Sensors , designed to detect and respond to obstacles in its path using low-cost sensors and microcontroller-based logic. The system utilizes two ultrasonic sensors positioned at the front of the vehicle to continuously monitor the surroundings and measure the distance of approaching obstacles. When an object is detected within a predefined safe distance, the system automatically stops the vehicle using the L293D motor driver, simulating an auto-braking mechanism. Additionally, a buzzer is activated to provide an audible warning to indicate the presence of an obstacle. The core of the system is controlled by an Arduino Uno, which processes sensor data and makes real-time movement decisions. This prototype demonstrates how basic embedded systems and sensors can be integrated to create a functional, cost-effective safety feature, highlighting its potential application in smart vehicles and autonomous navigation systems.
