Fitness Step Counter Kit with Arduino Nano & Flex Sensors — Dual-Mode Wearable for Physiotherapy and Activity Tracking

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Most fitness trackers only count steps. This kit lets you build a wearable that also quantifies how your fingers move—critical for physiotherapy compliance after hand injuries or surgeries. Four flex sensors, mounted on a glove, continuously measure metacarpophalangeal joint angles during prescribed exercises, while the onboard MPU6050 tracks steps in parallel. Logged with real‑time timestamps to a microSD card, the data shows exactly when and how thoroughly a rehabilitation routine was performed.

What You'll Build

You’ll assemble a left‑ or right‑hand glove instrumented with four 2.2‑inch flex sensors (index through little finger). An Arduino Nano reads bending angles, the MPU6050 detects walking steps, and a DS3231 real‑time clock stamps every data point. All readings appear on a 0.96‑inch OLED display and save to a microSD card. The result is a self‑contained, rechargeable logger that a patient or athlete wears during a therapy session; later, a clinician or coach can review the CSV log to verify compliance and progress.

What You'll Learn

• Calibrating flex sensors with voltage dividers and mapping bend angles to joint range of motion
• Reading MPU6050 accelerometer/gyroscope data and implementing a step‑detection algorithm on an Arduino Nano
• Interfacing a DS3231 RTC for microsecond‑accurate time‑stamping and logging structured data to a microSD card
• Designing a wearable prototype on a PCB board, managing battery power with a TP4056 charger, and soldering compact connections

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This advanced project fits B.Tech ECE, EEE, or Biomedical Engineering students exploring wearable health tech for Smart India Hackathon or capstone projects. It’s equally valuable for ATL Tinkering Lab mentors designing therapy devices for rehabilitation centres, and for physiotherapy researchers who need a low‑cost data logger to track hand function objectively. If you’ve built intermediate Arduino projects and want to move into real‑world sensing systems, this kit bridges classroom electronics with clinical need.
