14********************

16This project configures the max30101 sensor on the :ref:`hexiwear` board to
17enable the green LED and measure the reflected light with a photodiode. The raw
18ADC data prints to the console. Further processing (not included in this
19sample) is required to extract a heart rate signal from the light measurement.
