Intelligent Automotive Horn System 🚗🔊

Overview

This project implements an intelligent automotive horn system that dynamically controls horn direction and intensity based on environmental noise, vehicle orientation, proximity, and geofenced no-honking zones.

Problem Statement

Unnecessary honking contributes significantly to urban noise pollution and driver stress.

Proposed Solution

• Adaptive horn volume using ambient noise levels
• Directional horn control based on vehicle angle
• Automatic horn suppression in no-honking zones (GPS-based)
• Proximity awareness using ultrasonic sensing

System Components

• Arduino Uno
• HC-SR04 Ultrasonic Sensor
• Dual Piezo Buzzers
• Simulated sensors using potentiometers

Features Implemented

• Psychoacoustic horn volume control
• Directional horn logic (Left / Right / Front)
• Geofenced no-honking zones
• Obstacle proximity indication

Applications

• Smart vehicles
• Noise pollution control
• Intelligent transportation systems
