Code Documentation

Arduino UNO 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 UNO. 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 MLX90614 sensor and process it as needed.
