Build a Smart Cane for the Visually Impaired with Arduino Nano and Dual HC-SR04 Sensors

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit turns a standard walking cane into an intelligent navigation aid. Two HC-SR04 ultrasonic sensors mounted at the cane tip scan ahead and, through an Arduino Nano, drive coin vibration motors inside the handle. The haptic intensity increases smoothly as obstacles come within 2 metres, giving the user a discreet, proportional sense of distance without any audible alarms or headphone dependency - ideal for navigating crowded streets, doorways, or unfamiliar indoor spaces.

What You'll Build

A fully functional assistive cane that vibrates to indicate nearby obstacles in real time. You'll mount dual ultrasonic sensors at the base, wire everything to a compact Arduino Nano on a prototype PCB, and integrate the vibration actuators into the handle grip. The final device is battery-powered, rechargeable, and built entirely from the components in this box.

What You'll Learn

• Integrating multiple HC-SR04 ultrasonic distance sensors with Arduino for parallel obstacle detection
• Programming PWM-driven proportional haptic feedback using BC547 transistor drivers
• Designing low-power wearable assistive circuits with 3.7V LiPo and TP4056 charging module
• Soldering and assembling a rugged prototype on PCB boards for real-world use
