Follow Milos as he builds a DIY ECG based heart rate chest strap using an AD8232 module and an ESP32 C3, then tests it during a real run to compare its performance with common fitness tracking gear. He walks through the signal capture process, explains how the Pan Tompkins algorithm detects heartbeats and shows how the device streams data to a phone over BLE just like a commercial sensor. The project explores what works, where the readings drift and what he plans to improve in the next version: bit.ly/48BOmEW
