Automated Braking System

Project Overview 🚗

The Automated Braking System is a prototype designed to enhance vehicle safety by automatically applying brakes when obstacles are detected. Developed using C programming on the LPC2148 ARM7 microcontroller with Keil IDE.

Key Features 🔑

• Obstacle Detection: Utilizes an ultrasonic sensor (HC-SR04 based) to detect obstacles.
• Automatic Braking: Automatically stops the vehicle when an obstacle is within a predefined range.
• Microcontroller Implementation: Programmed on the LPC2148 ARM7 microcontroller.
• User Interface: Includes an LCD display for system status.
