This is the project you'll complete - a fully integrated assistive cane engineered for guiding a visually impaired user. The two HC-SR04 sensors create a detection zone up to 2 meters ahead, while the coin vibration motors ramp up intensity as an obstacle gets closer, delivering intuitive, proportional feedback without a single audible beep.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou will assemble and calibrate a complete wearable assistive device on a standard walking cane. The upward-angled sensor catches overhanging branches and signboards. The forward-facing sensor detects walls, vehicles, and people at ground level. When an obstacle is within range, the corresponding motor vibrates with a strength that mirrors urgency - a gentle buzz for distant objects, a sharp pulse for immediate hazards. You'll solder the circuit on a compact prototype board, housing the Arduino Nano, TP4056 charging module, and LiPo battery in a slim enclosure at the handle.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision ultrasonic ranging with dual HC-SR04 sensors, including echo pin timing and interference mitigation between sensors\u003c\/li\u003e\n  \u003cli\u003ePWM-based proportional haptic feedback control using BC547 transistors to drive coin vibration motors without overloading Arduino pins\u003c\/li\u003e\n  \u003cli\u003eWearable electronics integration - managing weight, battery life, and durable soldered connections on a moving cane\u003c\/li\u003e\n  \u003cli\u003eUser-centric calibration logic: mapping raw distance to vibration intensity curves that feel intuitive under real mobility scenarios\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eArduino Nano\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHC-SR04\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCoin Vibration Motor\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBC547 Transistor\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e1N4007 Diode\u003c\/td\u003e\n\u003ctd\u003e4\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e100?
