Nano Wristband Step Counter Kit with Arduino Nano + MPU6050
Build a Wrist‑Worn Step Counter with Arduino Nano & MPU6050 — See Steps Live on 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.
Imagine wearing a wristband you built yourself that counts every step you take. This kit turns an Arduino Nano and an MPU6050 motion sensor into a personal step counter you can slip on like a watch. The bright 4‑digit display shows your daily total, and the tiny size means it never gets in your way — a perfect first project for anyone curious about wearable electronics.
What You'll Build
You’ll assemble a rechargeable step‑counter wristband that detects wrist swings using an accelerometer, processes the data with an Arduino Nano, and updates a TM1637 7‑segment display in real time. A DS3231 real‑time clock adds the ability to track daily counts. The whole circuit fits on a prototype board and is held on your wrist with the included Velcro strap.
What You'll Learn
- How to read acceleration data from an MPU6050 sensor over I2C and interpret movement patterns.
- Writing Arduino code to detect steps using threshold‑based algorithms on acceleration magnitude.
- Interfacing a TM1637 4‑digit 7‑segment display to show live step counts.
- Soldering components onto a PCB prototype board and assembling a wearable device with a rechargeable LiPo battery.

Who This Kit Is For
CBSE Class 5–12 students will love the hands‑on experience for ATL Tinkering Lab or science fair projects. B.Tech ECE/EEE first‑year students at IITs, NITs, VIT, or BITS can grasp practical microcontroller‑based wearable design. It’s also a fantastic parent‑child weekend build for kids as young as 10, with adult supervision for soldering.
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?
Open the AI chat from the QR code; it recognises your kit and guides you through debugging step by step. If you need a human touch, WhatsApp our team for a personalised reply within a few hours.
Can I wear this step counter while running?
Yes, the MPU6050 reliably detects the stronger wrist accelerations of running. The provided step‑detection code includes a simple tuning value you can adjust to match different activities.
How long does the battery last, and is it rechargeable?
The included TP4056 module safely charges the 500mAh LiPo via any USB port. A full charge powers the wristband for 6–8 hours of continuous step counting.
Does this kit teach coding or just assembly?
It’s a full coding experience. The AI companion explains every line of the Arduino sketch — from reading sensor registers to updating the display — so you understand how the step‑counting logic works, not just how to solder it together.
MPU6050 on Nano counts steps from wrist acceleration. 7-segment display shows daily step count.
