From the project

A custom Arduino Nano-based pulse oximeter and heart rate monitor board featuring a MAX30102 sensor, an SSD1306 OLED display, and a hardware-debounced 3-button interface

This repository contains the PCB design files and schematic for a custom health-tracking board, as seen in the routing. Built around the Arduino Nano, this project functions as a standalone pulse oximeter. It reads biometric data via I2C from a MAX30102 sensor and displays real-time blood oxygen saturation and heart rate metrics on an SSD1306 OLED screen.
