Resting Heart Rate Monitor Variant 12 Kit with Arduino Nano + LED
Build Your Own Resting Heart Rate Monitor with Arduino Nano and Optical Pulse Sensor
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 placing your finger on a small sensor and seeing a row of red LEDs blink out your resting heart rate. That's exactly what you'll create with this beginner-friendly kit. Designed around the MAX30102 optical pulse oximeter and the compact Arduino Nano, you'll assemble a working health monitor that measures your beats per minute over 30 seconds and displays the average — a simple one-button start that launches you into the world of medical wearables.
What You'll Build
You'll put together a breadboard-based heart rate monitor that mimics a real wearable's core function. Place your fingertip on the MAX30102 sensor, press the start button, and wait while the Arduino collects 30 seconds of data. When it's done, the two 5mm red LEDs flash a pattern — each blink counts out the average BPM. The whole unit runs from a 9V battery and shows how compact health tech can be, making it a standout project for a science exhibition or just exploring how your body works.
What You'll Learn
- How optical heart rate sensors use light to detect blood volume changes
- Reading I2C sensor data with an Arduino Nano
- Calculating and averaging BPM from raw pulse signals
- Outputting information visually using LED blink patterns

Who This Kit Is For
This kit is perfect for middle- and high-school students exploring biology-tech crossovers — think CBSE Class 9–12 science fairs or ATL Tinkering Lab innovators. First-year B.Tech ECE or BME students will also find it a gentle introduction to biosensors. Even young makers under 15 can complete it with adult supervision, gaining hands-on confidence in circuits and coding without a single dangerous tool.
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 for this kit, or send a WhatsApp message to our support team — both options provide instant, clear guidance.
Do I need a computer to load the code onto the Arduino Nano?
Yes, you'll need a laptop or PC with the free Arduino IDE installed. The AI companion includes the exact code and a walkthrough for uploading it.
How accurate is the BPM measurement?
The MAX30102 can detect beats with clinical-grade optical precision. Our code averages 30 seconds of data to smooth out momentary noise, giving you a reliable resting rate typical of a simple medical device.
Can I modify the project to show results on a display or send data to my phone?
Absolutely. Once you understand the basic circuit, the Arduino Nano can be connected to an OLED screen or a Bluetooth module. The kit gives you the foundational knowledge to expand into full wearables.
MAX30102 measures resting BPM over 30 seconds and shows average. Simple one-button measurement.
