Wrist-Worn ECG Monitor Kit with Arduino Nano + LED
Wrist-Worn ECG Monitor Kit: Build a Portable Cardiac 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.
Move beyond textbook theory — construct a fully functional wrist-worn electrocardiogram that captures, displays, and records your heart’s rhythm in real time. Using the clinical-grade AD8232 front-end, an OLED screen, and microSD storage, you’ll create a compact wearable that rivals commercial health gadgets. This kit is engineered for university projects, hackathons, and the aspiring biomedical engineer.
What You'll Build
A battery-operated, wrist-mounted ECG monitor that displays a scrolling waveform on a crisp 0.96-inch OLED display and timestamps every beat to a microSD card. Place the included electrodes on your wrist, power up, and watch your heart’s P-QRS-T complex unfold. The data is ready for analysis in MATLAB, Python, or any tool, making it a perfect platform for prototype development or academic research.
What You'll Learn
- Acquire single-lead ECG signals using the AD8232 analog front-end with proper electrode placement
- Filter and amplify bio-signals to extract clean waveforms using on-board RC components and Arduino code
- Drive a 0.96-inch OLED via I2C to plot real-time streaming data
- Log time-stamped physiological data to a microSD card using the DS3231 RTC for accurate sample timing

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?
If you get stuck, scan the QR code on the box to access your AI build companion trained specifically on this ECG kit. It will walk you through debugging step by step. You can also message us on WhatsApp and get a reply within hours.
Is wrist-based ECG accurate enough for real monitoring?
Single-lead wrist ECG provides diagnostic-quality rhythm monitoring and is widely used in wearable health devices for heart rate variability and arrhythmia detection. While it cannot replace a 12-lead clinical ECG, it is perfect for educational and research purposes.
Can I modify the kit to send data to my phone or a cloud server?
The Arduino Nano does not have built-in wireless, but the PCB prototype boards make it easy to add a Bluetooth or WiFi module. Many students integrate an HC-05 or ESP8266 to stream data to a mobile app. Our AI companion includes guidance on these modifications.
Do I need prior soldering experience?
Yes, this is an advanced kit. You'll need basic soldering skills to assemble the PCB boards. If you're new to soldering, the included iron and wire are of good quality, and our AI companion provides solder tips.
AD8232 ECG front-end captures single-lead ECG from wrist electrodes. Displays waveform on OLED and logs to SD.
