This document summarizes a project on designing an automatic braking system to avoid accidents. The system uses sensors that detect obstructions in front of the vehicle and immediately engage the brakes. When an infrared emitter detects an object and the reflected light hits a receiver, a signal is sent to a motor that controls the brakes. The key components are a DC motor, diode, LED, phototransistor, and IC chip. The goals are to stop the vehicle safely in the shortest possible distance with minimal effort from the driver.
