Code Documentation

Arduino UNO Code

void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  Serial.println("Setup");
}

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

This code initializes the serial communication at a baud rate of 9600 in the setup() function and prints "Setup" to the serial monitor. The loop() function is currently empty and can be filled with the main logic to be executed repeatedly.
