TFT Realtime ECG Waveform Kit with Arduino Mega
Build a Real-Time Scrolling ECG Waveform with BPM Overlay — Arduino Mega & TFT Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your workbench into a biomedical diagnostics lab. With this kit, you'll capture your heart's electrical signals, filter them with the AD8232, and render a real-time scrolling waveform on a TFT screen — complete with an accurate beats-per-minute overlay. Perfect for Smart India Hackathon healthcare challenges, CBSE biology/electronics experiments, or B.Tech ECE mini-projects.
What You'll Build
A working ECG monitor that graphs your heartbeat as a moving trace on a 1.8-inch colour display. The system continuously updates at 25 frames per second, drawing a clean waveform and instantly calculating BPM from the R-peak intervals. You'll plug electrode patches onto your chest, and within seconds, see your live heart data rendered in crisp pixels.
What You'll Learn
- ECG signal acquisition using the AD8232 analog front-end and its integrated filter.
- Real-time data streaming and circular buffering on Arduino Mega's ATmega2560.
- TFT ST7735 graphics programming: drawing a scrolling waveform and dynamic BPM overlay.
- Biomedical sensor integration, noise reduction, and R-peak detection algorithms.

Who This Kit Is For
Designed for CBSE Class 12 students working on bio-electronics investigatory projects, first-year B.Tech ECE/Biomedical students tackling signal processing labs, and Smart India Hackathon teams building affordable health monitors. Also ideal for ATL Tinkering Labs and hobbyists curious about medical device prototyping.
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?
Just scan the QR code on the box to access the AI build companion trained on this exact project. If you need human help, WhatsApp our support team — we typically respond within an hour during Indian business hours.
Can I use this kit to measure heart rate during exercise?
Yes, the AD8232 is designed for motion-tolerant applications. However, for highly dynamic activities, we recommend securing the electrode patches firmly and using the provided filtering capacitors to reduce motion artifacts.
Is it safe to connect this kit to a patient?
This kit is a learning tool for educational purposes only. It's not medically certified. Always use battery power and never connect electrodes to anyone with a pacemaker
AD8232 ECG module streams to TFT at 25fps. Scrolling waveform with BPM overlay.
