Arduino-Powered Fitness Heart Rate Monitor Kit v2: Live BPM on OLED Display

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 1-5 days.

Transform a few simple components into a wearable-inspired heart rate monitor that displays live BPM on a crisp OLED screen. This kit lets you measure heart rate during rest, after light activity, and track recovery rates — the same metrics that fitness wearables use, now built by your own hands.

What You'll Build

You'll assemble a compact, Arduino-powered heart rate monitor that clips onto a finger or wrist. The MAX30102 optical sensor captures pulse signals, processed instantly to show real-time beats per minute on a 0.96-inch OLED display. This isn't a simulation — you'll see your own heart rate change from resting around 70 bpm to elevated after jumping jacks, then watch it return to baseline during recovery.

What You'll Learn

• Interface the MAX30102 pulse sensor using Arduino's I2C protocol
• Process raw optical heart rate signals into clean BPM readings
• Display real-time data on a 128x64 OLED screen
• Understand cardiac physiology: resting, active, and recovery heart rates
