Project description
Cardia — A W5100 Ethernet ECG Web Monitor Open-source project curation | Original work by Nisa Maaşoğlu The illustrative artwork is AI-generated. The dashboard image is an original DEMO screenshot; the system diagram is a simplified explanation based on the source. English 01 — Project Overview Cardia connects an AD8232 ECG front end and an Arduino Uno to a browser dashboard through wired Ethernet. Its appeal is the complete signal path: the microcontroller acquires an analog signal, detects R-peaks, estimates heart rate, and exposes the results as JSON for a lightweight web interface…
