We’ve seen a number of heart rate monitoring projects on Hackaday, but [Peter’s] electrocardiography (ECG) Instructable really caught out attention. If you’ve followed Hackaday for any period of time, ...

This Arduino project reads ECG signals using an analog input and visualizes them. It includes signal filtering, peak detection, and real-time plotting. Upload the ecg_arduino.ino file to your Arduino.

Real-time ECG waveform monitoring using an ESP32 and AD8232 ECG sensor. The ESP32 samples ECG signal at 250 Hz and streams the data via WebSockets to a clean, modern web UI for live visualization.

When Analog Devices introduced the AD8232 single-lead heart-rate monitor analog front end (AFE) in August, it doubled down on the design effort it put into the ADAS1000 AFE for diagnostic-quality ...
