#include Wire.h
#include MAX30100_PulseOximeter.h

#define REPORTING_PERIOD_MS     1000

 PulseOximeter is the higher level interface to the sensor
 it offers
   beat detection reporting
   heart rate calculation
   SpO2 (oxidation level) calculation
PulseOximeter pox;

uint32_t tsLastReport = 0;

 Callback (registered below) fired when a pulse is detected
void onBeatDetected()
{
    Serial.println(B1);
}

void setup()
{
    Serial.begin(115200);

     Initialize the PulseOximeter instance and register a beat-detected callback
     The parameter passed to the begin() method changes the samples flow that
     the library spews to the serial.
     Options
       PULSEOXIMETER_DEBUGGINGMODE_PULSEDETECT  filtered samples and beat detection threshold
       PULSEOXIMETER_DEBUGGINGMODE_RAW_VALUES  sampled values coming from the sensor, with no processing
       PULSEOXIMETER_DEBUGGINGMODE_AC_VALUES  sampled values after the DC removal filter

     Initialize the PulseOximeter instance
     Failures are generally due to an improper I2C wiring, missing power supply
     or wrong target chip
    if (!pox.begin(PULSEOXIMETER_DEBUGGINGMODE_PULSEDETECT)) {
        Serial.println(ERROR Failed to initialize pulse oximeter);
        for(;;);
    }

    pox.setOnBeatDetectedCallback(onBeatDetected);
}

void loop()
{
     Make sure to call update as fast as possible
    pox.update();

     Asynchronously dump heart rate and oxidation levels to the serial
     For both, a value of 0 means invalid
    if (millis() - tsLastReport  REPORTING_PERIOD_MS) {
        Serial.print(H);
        Serial.println(pox.getHeartRate());

        Serial.print(O);
        Serial.println(pox.getSpO2());

        tsLastReport = millis();
    }
}
