Fermion: MAX30102 Heart Rate and Oximeter Sensor

1. Example Code for Arduino - Get Heart Rate and Blood Oxygen Data

In this sample, the heart rate and blood oxygen data is obtained through interrupts, and the heart rate is measured when the sensor's red light is on. If the interrupts is shielded, the data can still be obtained, but during the update the data obtained does not change.
