3. Configure the MAX30105 object in Arduino with basic settings (check the datasheet).
4. Initialize the MAX30102 sensor for data reading.
5. Read the heart rate and SpO2 values from the MAX30102 sensor.
6. Display the data in serial monitor or through web interface (optional).
7. Calibrate the MAX30102 sensor to improve measurement accuracy.

Example code

// Includi la libreria Adafruit MAX30105
#include <Wire.h>
#include <Adafruit_MAX30105.h>
// Inizializza l'oggetto MAX30105
Adafruit_MAX30105 max30105 = Adafruit_MAX30105();
void setup() {
  Serial.begin(9600);
  if (!max30105.begin(Wire)) {
    Serial.println(F("Errore: Non riesco a trovare il MAX30105"));
    while (1); // Blocca l'esecuzione
  }
}
void loop() {
  max30105.startHeartBeat(64, 80);
  delay(2000);
  uint32_t heart_rate = max30105.heartRate();
  Serial.print("Frequenza cardiaca:");
  Serial.println(heart_rate);
}
