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 settings, and the loop() function is where you place the code that you want to run continuously. Currently, both functions are empty and need to be filled with the appropriate logic to control the relay module and bulbs.
