Build a Wireless Prosthetic Finger Controller with Arduino and Flex 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 enables you to create a functional prosthetic finger control system where flex sensors on a glove wirelessly transmit finger curl data to a bionic hand, driving five servo-actuated digits. Whether you're an ECE student exploring electromyography alternatives or a robotics enthusiast building an assistive prototype, this project bridges bio-signal sensing with real-time motion control. You'll emerge with a working model that replicates natural finger flexion, ideal for hackathon demonstrations or final-year submission.

What You'll Build

A wireless glove-to-hand system that maps each finger's bend to a servo-driven prosthetic digit. The glove unit houses five flex sensors and an Arduino Nano transmitter, while the bionic hand uses a second Nano to decode Bluetooth signals and articulate 3D-printed finger links. You'll tune proportional control loops and mechanical alignment until the prosthetic mirrors your own hand movements with minimal delay.

What You'll Learn

• Interfacing flex sensors with Arduino for precise analog signal acquisition
• Establishing Bluetooth serial communication between two Arduino Nanos (HC-05 master-slave)
• Designing servo control algorithms for proportional finger actuation
• Integrating mechanical finger links with 3D-printed parts and sensor calibration
