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 sensors and modules, and the loop() function is where you place the main logic that runs repeatedly. You will need to add the specific initialization and logic for each sensor and module based on your application requirements.
