Abstract

Mobility remains one of the greatest challenges faced by visually impaired individuals, with conventional white canes offering limited protection against head-level or distant obstacles.This project addresses that gap by providing a lowcost, Arduino Nano-based smart cane that detects obstacles in real time and alerts users through progressive haptic and auditory feedback.The system integrates an HC-SR04 ultrasonic sensor for obstacle detection, a vibration motor with cubic PWM mapping for smooth intensity control, and an active buzzer with dynamic cadence that tightens as proximity decreases, culminating in an emergency mode (maximum vibration + continuous tone) at very close range (
