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.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eA 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.
