Biosignal ECG Monitor Kit Kit with Arduino Nano + LED
Capture Your Own Heart’s Electrical Signature with the Arduino Nano & AD8232 ECG Monitor 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.
This kit turns an Arduino Nano and a medical-grade AFE into a real-time ECG monitor that displays the P-QRS-T waveform and beats-per-minute on an OLED. Build a portable data-logging biosensor you can wear during light activity — and understand the analogue front-end design behind clinical ECG machines. From single-lead electrode placement to noise filtering and R-peak detection, every stage of biomedical embedded design is demystified in a hands-on format.
What You'll Build
A battery-powered, single-lead electrocardiograph that picks up the heart’s mV-level electrical signal through disposable electrode patches. The AD8232 front-end amplifies and filters the biopotential; the Arduino Nano samples it, computes heart rate via R-R interval, and drives a 0.96-inch OLED showing the scrolling waveform and numerical BPM. All capture sessions are time-stamped by a DS3231 RTC and written to a MicroSD card for later analysis in MATLAB or Python.
What You'll Learn
- Configure the AD8232 instrumentation amplifier for different gain and filter responses
- Acquire single-lead ECG with proper electrode placement and skin preparation
- Implement real-time peak detection and BPM calculation on a microcontroller
- Log timestamped biosignal data to MicroSD using I2C and SPI peripherals

Who This Kit Is For
Designed for B.Tech ECE, EEE, and Biomedical Engineering students working on final-year projects, Smart India Hackathon prototypes, or research in non-invasive cardiac monitoring. Equally suited for PG scholars at IIT/NIT/VIT/BITS exploring embedded biosignal acquisition, and for ATL mentors who need a reliable, pre-validated ECG front-end that saves weeks of circuit troubleshooting.
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?
Your AI companion walks you through every connection, code upload, and waveform interpretation. Still stuck? Reach out on WhatsApp and our engineer will guide you directly.
Can I modify the design to use a different microcontroller?
The kit is optimized for Arduino Nano, but the AD8232, OLED, and RTC use standard I2C/SPI protocols. You can adapt the code and wiring for an ESP32, STM32, or Raspberry Pi Pico with minimal effort.
Is the ECG signal clinically usable?
This is a single-lead, educational-grade monitor useful for heart rate variability studies and waveform morphology observation. It is not a medical device and should not be used for diagnosis.
How long does the battery last during continuous monitoring?
The 500 mAh LiPo powers the system for approximately 4-5 hours of continuous ECG streaming. The TP4056 module charges the battery via any micro-USB source in about 1.5 hours.
AD8232 ECG front-end captures single-lead cardiac signal. OLED shows waveform and heart rate BPM.
