Build a Real-Time ECG, SpO2 & GSR Dashboard with Arduino Mega

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

This kit turns an Arduino Mega into a multi-parameter patient monitor, capturing your heart’s electrical activity, blood oxygen levels, and emotional sweat response—all plotted live on a bright 2.4-inch TFT screen. For B.Tech biomedical students and health tech hackers, it’s a hands-on way to understand front-end analog signal conditioning, multi-channel ADC multiplexing, and GUI design without needing an oscilloscope or MATLAB.

What You'll Build

You’ll assemble and code a dashboard that acquires ECG via AD8232, SpO2 via MAX30102, and galvanic skin response via a voltage divider and ADS1115 ADC. The ILI9341 display renders three scrolling waveforms simultaneously: a real-time ECG trace, a photoplethysmogram for heart rate and SpO2 calculation, and a skin conductance line that rises with stress. All sensor fusion and screen refreshing is done by the Arduino Mega, giving you a compact, portable health monitor ready for demo or prototype integration.

What You'll Learn

• Acquiring and conditioning biopotential signals (ECG) using an instrumentation amplifier and right-leg drive.
• Interfacing optical pulse oximetry sensor (MAX30102) via I2C for raw red/IR data, then converting to heart rate and SpO2.
• Measuring galvanic skin response with a simple voltage divider, amplified by the ADS1115 16-bit ADC for high resolution.
• Programming a TFT display library to render multiple real‑time waveforms with smooth scrolling and overlays.
