Arduino Bluetooth Prosthetic Finger Kit - Wireless Bionic Hand Builder
Arduino Bluetooth Prosthetic Finger Control Kit - Build a Wireless Bionic Hand System
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 advanced kit turns a glove into a wireless controller for a bionic hand-flex sensors map finger curl to servo-driven prosthetic fingers over Bluetooth. Designed for final-year biomedical projects, hackathon prototypes, and assistive technology research, it gives you a fully functional prosthetic finger control system and deep insight into embedded wireless design.
What You'll Build
You'll assemble two Arduino units: one on a glove that digitizes the bending of five flex sensors, and one on the forearm that receives data via Bluetooth and drives five SG90 servos. The servos pull 3D-printed finger links, creating proportional, real-time finger movement. The result is a wearable, untethered bionic hand that you can demonstrate as a working prototype.
What You'll Learn
- Mapping flex sensor resistance to finger joint angles and implementing linearization with fixed resistors
- Establishing a robust Bluetooth serial link between two Arduino Nanos using HC-05 modules
- Controlling five servo motors simultaneously with PWM and parsing wireless command packets
- Integrating soldered circuits, 3D-printed mechanics, and embedded code into a cohesive biomechatronic system

Who This Kit Is For
B.Tech ECE and EEE students taking up final-year projects in assistive technologies or embedded biomedical systems. Smart India Hackathon teams prototyping wireless human-machine interfaces. Makers at IIT, NIT, VIT, and BITS Pilani engineering clinics who need a ready-to-integrate bionic finger subsystem for larger robotic hand research.
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?
The AI companion provides step-by-step troubleshooting, and you can send photos or code snippets via WhatsApp for personalized help.
Can I use this for my B.Tech major project or hackathon?
Absolutely. The kit delivers a complete working prototype you can demonstrate, and the schematics and code are yours to extend.
Are the flex sensors pre-soldered?
No, you'll solder the sensors onto the PCB along with the resistors and capacitors-a critical skill the build teaches.
What Bluetooth range can I expect between glove and arm?
With the HC-05 modules, expect a reliable 8-10 meter range in open air, more than enough for a wearable system.
Audio - Flex sensors map finger curl to servo prosthetic finger positions. Wireless glove-to-arm BT link.
