Nano Heart Rate Wristband Kit with Arduino Nano + LED
DIY Heart Rate Wristband Kit with Arduino Nano & OLED – BPM on Your Wrist
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Slip this 3D-printed wristband onto your hand and watch your real-time heart rate appear on the OLED display — a fully wearable, rechargeable BPM monitor you code and assemble yourself. The MAX30102 optical sensor captures your pulse, the Arduino Nano crunches the data, and the OLED screen shows beats per minute clearly. It's the perfect blend of health tech creativity and hands-on electronics for school projects, science fairs, or simply impressing friends.
What You'll Build
You'll create a compact wristband that continuously reads your pulse using the MAX30102 sensor, processes the signal on an Arduino Nano, and displays beats per minute on a bright 0.96-inch OLED screen. The built-in 500mAh LiPo battery and TP4056 charging module let you wear it untethered, making it a genuine portable health companion. All components fit neatly into a custom-designed 3D-printed band that you assemble in a single afternoon.
What You'll Learn
- Interfacing the MAX30102 pulse oximetry sensor with Arduino and reading raw PPG data
- Driving an I2C OLED display to show real-time heart rate values
- Soldering connections on a proto-board and assembling a wearable circuit
- Integrating a lithium-polymer battery with a TP4056 charging module for safe, portable power

Who This Kit Is For
Young innovators in ATL Tinkering Labs and school electronics clubs will love crafting a real wearable that tracks heart rate. It’s an ideal hands-on project for CBSE students exploring sensor integration and for Smart India Hackathon junior challenges where portable health solutions stand out. Even first‑year B.Tech ECE students find it a motivating introduction to embedded health monitoring.
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?
Our AI companion walks you through every connection, and you can chat with our team on WhatsApp if you need a human touch.
Can this wristband measure oxygen saturation (SpO2) too?
The kit is designed to display heart rate. The MAX30102 sensor can read SpO2, and the AI companion includes hints to extend the code if you want to experiment with blood oxygen levels.
Is soldering safe for a 10‑year‑old?
We include a soldering iron with adjustable temperature and lead‑free solder. We strongly recommend adult supervision for builders under 12. The AI companion also suggests cold solder‑free connection methods as a safer alternative.
Does the wristband fit all sizes?
The 3D‑printed wristband is designed for medium‑size wrists (ages 8+). It includes an adjustable Velcro strap for a snug fit. If you need a smaller or larger version, the AI companion includes a link to request a customized STL file.
