MAX30102 HR + SpO2 sensor

• GND is connected to GND of the Arduino Mega 2560.
• VIN is connected to 5V of the Arduino Mega 2560.
• SCL is connected to D21/SCL of the Arduino Mega 2560.
• SDA is connected to D20/SDA of the Arduino Mega 2560.

Code Documentation

Arduino Mega 2560 Code

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

This code is a basic template for the Arduino Mega 2560. The setup() function is where you initialize your sensor and any other peripherals. The loop() function is where you will write the main logic to read data from the MAX30102 sensor and process it.
