Blind Navigation Ultrasonic Cane Kit with Arduino Nano + Ultrasonic
Build a Life-Changing Ultrasonic Navigation Cane with Arduino Nano — Assistive Tech That Vibrates Distance
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 isn’t just another sensor tutorial. You’ll engineer a fully functional walking cane that helps visually impaired users detect obstacles and feel distance through vibration intensity. Dual HC-SR04 ultrasonic sensors scan ahead, and the Arduino Nano translates object ranges into proportional haptic pulses — making navigation intuitive and hands-free. Perfect for final-year B.Tech projects, Smart India Hackathon prototypes, or serious hobbyists who want assistive technology that actually works.
What You'll Build
A modified white cane with two ultrasonic eyes, powered by a rechargeable LiPo battery. The handle houses a custom vibration feedback system: closer obstacles trigger stronger, faster vibrations, giving the user a spatial sense without audible beeps. You’ll solder the entire circuit onto a prototyping board, mount it discreetly on the cane, and calibrate for real-world use.
What You'll Learn
- Interfacing multiple HC-SR04 sensors with Arduino Nano and reading accurate distance data
- Designing haptic feedback with coin vibration motors, BC547 transistors, and flyback diodes
- Managing rechargeable 3.7V LiPo batteries with TP4056 charging modules safely
- Soldering and PCB prototyping for a wearable, assistive device form factor

Who This Kit Is For
B.Tech ECE/EEE students who need a standout final-year project with real social impact. Smart India Hackathon teams prototyping assistive devices under tight deadlines. ATL Tinkering Lab mentors guiding advanced learners. IIT, NIT, VIT, and BITS Pilani students who want to apply embedded systems to a genuinely helpful wearable. If you’re passionate about tech for inclusion, this kit gives you everything except the code — and our AI companion fills that gap.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code inside the kit to launch the AI companion, which walks you through calibration and debugging with project-specific prompts. If it’s after midnight, WhatsApp us — a real engineer from Bengaluru will reply within an hour.
I’ve never soldered before. Can I still build this?
This kit includes a soldering iron and solder wire, and the AI guide has a dedicated soldering primer for the PCB connections. Take your time; the joints are through-hole, and the companion shows you exactly where each component goes.
Can the cane differentiate between a wall and a moving person?
The dual-sensor setup can estimate obstacle width and motion when you implement the advanced algorithm discussed in the AI companion. By comparing echo times, you can trigger different vibration patterns for static vs. dynamic obstacles.
How do I present this as a B.Tech final-year project?
The companion provides a project report template, circuit diagrams, and a testing methodology document. It also suggests demo scenarios — like navigating a cluttered hallway blindfolded — that highlight your engineering and the social benefit.
HC-SR04 on cane detects obstacles within 2m and vibrates at proportional intensity to guide visually impaired user.
