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 used to initialize any settings or configurations, and the loop() function contains the main code that runs repeatedly. Currently, both functions are empty and need to be filled with the appropriate logic for controlling the LED and reading data from the BH1750 light sensor.
