Arduino Wrist Angle Monitor Kit - ADXL345 OLED for Exercise Form
Perfect Your Exercise Form with the Dual Axis Wrist Angle Monitor Kit (Arduino Nano + ADXL345)
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 gym enthusiast tracking wrist form during push-ups or a physiotherapy student analyzing joint angles, this kit equips you with a functional wearable that measures roll and pitch in real time. The ADXL345 accelerometer feeds precise tilt data to an Arduino Nano, while a vibrant OLED screen gives you instant visual feedback to correct your posture mid-set.
What You'll Build
You'll assemble a compact, breadboard-based wearable that senses wrist inclination along two axes. The ADXL345 continuously reads gravitational acceleration, and the Arduino Nano translates that into roll (side-to-side tilt) and pitch (forward-backward tilt). These angles appear as animated bar graphs on the 0.96-inch OLED, updating live. Simultaneously, the DS3231 RTC timestamps every reading and the MicroSD module logs it for post-workout analysis-creating a complete motion-tracking system you can strap to your wrist.
What You'll Learn
- Interface a 3-axis accelerometer (ADXL345) over I2C with Arduino Nano
- Visualize real-time inclination data on a 0.96-inch OLED display
- Log sensor readings with timestamps using a DS3231 RTC and MicroSD module
- Calibrate angle offsets for accurate exercise motion tracking

Who This Kit Is For
This kit is built for CBSE Class 11-12 students pursuing advanced electronics projects, B.Tech ECE/EEE undergraduates at IITs, NITs, VIT, and BITS Pilani working on wearable health tech, and ATL Tinkering Lab members developing Smart India Hackathon prototypes. It's equally valuable for physiotherapy students assessing wrist mobility or gym trainers who want a custom form-correction tool. If you can follow an intermediate wiring diagram and upload Arduino code, you're ready.
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 on the box to chat with our AI build companion, trained on step-by-step assembly and code for this exact kit. You can also reach us via WhatsApp for human support.
Can I actually wear this device during a workout?
Yes, the lightweight breadboard build can be secured to a wristband (not included) with Velcro or an elastic band. We recommend keeping it stationary during exercise for accurate readings.
How do I analyze the angle data after my workout?
The MicroSD module logs roll, pitch, and timestamps to a text file. Simply insert the SD card into your computer to view the data in any spreadsheet application.
Is this kit suitable for academic submissions?
Absolutely. The kit includes all core components for a working wearable angle monitor, and you can extend it with additional sensors or a PCB for your B.Tech project or CBSE practical exam.
ADXL345 measures roll and pitch of wrist during exercise. OLED shows live angle bars for form feedback.
