DIY Arduino Heart Rate Monitor – Open Source build with MAX30102 + 3D Printed Case

*DIY Arduino Heart Rate Monitor* – Built with the MAX30102 sensor, ESP8266 (D1 mini), and a custom 3D-printed case. This project is a submission to the *One Hertz Challenge*, hosted by Hackaday and DigiKey. 📺 *Chapters* 00:00 Introduction 00:23 Live demo – Heart rate monitor in action 00:52 Comparison with Apple Watch 01:18 The One Hertz Challenge 01:40 How pulse sensing works (MAX30102) 02:12 Parts overview 02:39 Case design in Fusion 360 03:24 Mounting display and microcontroller 03:46 Wiring and power supply 04:09 Soldering the MAX30102 connector 04:26 Assembling the device 05:04 Software: Arduino IDE & PlatformIO 05:31 Final demo & closing thoughts 🧠 *How it works* The device uses an infrared pulse sensor (MAX30102) to detect changes in light absorption caused by heartbeats. It then calculates the heart rate and displays it in both beats per minute (BPM) and frequency (Hz) on a compact OLED display. 🧰 *Components* Wemos D1 mini (ESP8266) MAX30102 pulse sensor SSD1306 OLED display (I2C) 3D-printed enclosure (STL available) 💾 *Source Code & 3D Files* 🔗 GitHub Repository: [https://github.com/lhm0/heart_rate_mo...] 🛠️ *Compatible With* Arduino IDE PlatformIO (VS Code) — Open `/software_platformIO/` folder and build via `platformio.ini` * Assembly* 🔗 instructables.com: [https://www.instructables.com/DIY-Ard...] 🔓 *License* Open Source — MIT License --- #Arduino #HeartRateMonitor #MAX30102 #ESP8266 #3DPrinted #OpenSource #DIYElectronics
