Understand Your Heart: Build a Pulse & Exercise Monitor with Arduino Nano

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

What if students could see the immediate effect of jumping jacks on their heartbeat, then watch how quickly it returns to normal? With this kit, they will. Using a MAX30102 pulse oximeter sensor and an Arduino Nano, you’ll build a portable device that records beats per minute before, during, and after exercise. The on-board real-time clock stamps each reading, while the crisp OLED screen displays live heart rate and a recovery curve—turning a simple workout into a data-driven science fair project.

What You'll Build

You’ll assemble a wearable-style biosensor that clips onto your finger. Once calibrated, it logs your resting BPM, then your heart rate during activity (e.g., 30 seconds of star jumps), and finally tracks the time it takes to return to baseline. All data is visualized on the OLED, giving you a clear picture of cardiovascular fitness. The device is compact, battery-powered, and ready for classroom demonstrations or science exhibitions.

What You'll Learn

• How optical heart rate sensors (MAX30102) work through photoplethysmography
• Writing Arduino code to read sensor data and control an OLED display
• Using a real-time clock (DS3231) to timestamp measurements for accurate recovery plots
• The physiology of heart rate, exercise stress, and recovery time
