Arduino Health Monitor
Arduino Health Monitor is a compact hardware project that reads heart-rate and blood-oxygen measurements from a MAX30100 pulse-oximeter sensor. An Arduino Uno processes the readings and presents the latest values on an I2C LCD for immediate local feedback.
Features
- Heart-rate measurement
- Blood-oxygen reading
- MAX30100 pulse-oximeter integration
- I2C LCD output
- Arduino Uno control logic
