Grip Strength Dynamometer Kit with Arduino Nano + LED
Build a Digital Grip Strength Dynamometer with Arduino Nano, FSR Sensor & OLED Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Whether you’re a physiotherapy student, a sports coach tracking athlete recovery, or a CBSE Class 12 student hunting for an innovative physics project, this kit transforms a simple squeeze into quantifiable data. You’ll assemble a hand-held dynamometer that reads grip force via a silicone-padded FSR, displays peak values instantly on an OLED, and timestamps every squeeze to a MicroSD—turning raw muscle effort into a training log you can analyze later.
What You'll Build
You’ll create a compact, battery-powered grip meter. The FSR under the silicone pad outputs an analog voltage proportional to force; the Arduino Nano samples it hundreds of times per squeeze, calculates the maximum, and pushes the reading to the bright 0.96-inch OLED. Simultaneously, the DS3231 real-time clock appends the exact date and time to each log entry saved on the MicroSD card, giving you a complete history of grip strength across multiple sets.
What You'll Learn
- Interface an FSR sensor and calibrate the force-to-voltage curve for consistent measurements
- Drive a 0.96-inch OLED display over I2C to show real-time peak force in Newtons
- Integrate a DS3231 RTC module to timestamp sensor events with second-level accuracy
- Write structured data (timestamp, peak force) to a MicroSD card for training log analysis

Who This Kit Is For
Designed for CBSE Class 11–12 students creating sensor-based physics investigatory projects, B.Tech ECE/EEE undergraduates building semester mini-projects, and participants in Smart India Hackathon needing a rapid health-tech prototype. ATL tinkering labs will find it a perfect entry point into wearable sensing. Coaches and physiotherapy enthusiasts can use the data logging to monitor grip strength trends objectively.
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 to chat with the AI companion trained on this kit; it can walk you through wiring, code debugging, and calibration. You can also reach us on WhatsApp for human backup.
Can I display force in kilograms or pounds instead of Newtons?
Yes. The AI companion includes calibration snippets that convert the raw analog reading to kg or lb. You simply adjust the scaling factor in the code to match your preferred unit.
How do I view the logged training data?
Remove the MicroSD card and insert it into any computer. A CSV file lists each squeeze with its timestamp and peak force, ready for spreadsheet analysis or graphing your progress over time.
Is this kit suitable for a CBSE science exhibition?
Absolutely. It demonstrates real-world sensor physics, microcontroller programming, and health-monitoring applications, making it a compelling ATL or CBSE physics project that judges find relevant and innovative.
FSR under silicone pad measures grip force. OLED shows peak force per squeeze. Logs training sets.
