Day 2 Lesson 02: Hello World!

In this part 2 of day 2, we move to the Tinkercad visual programming and Arduino simulator to work on our blink script, getting it to output debugging messages to the serial monitor, before moving to the desktop IDE to do some more edits and see how the serial monitor works for real.

Code

void setup()
{
  pinMode(13, OUTPUT);
  Serial.begin(9600);
  Serial.println("Hello World!");
}
void loop()
{
  digitalWrite(13, HIGH);
  Serial.println("Led On");
  delay(100); // Wait for 100 millisecond(s)
  digitalWrite(13, LOW);
  Serial.println("Led Off");
  delay(100); // Wait for 100 millisecond(s)
  
  digitalWrite(13, HIGH);
  Serial.println("Led On");
  delay(500); // Wait for 500 millisecond(s)
  digitalWrite(13, LOW);
  Serial.println("Led Off");
  delay(500); // Wait for 500 millisecond(s)
  
  digitalWrite(13, HIGH);
  Serial.println("Led On");
  delay(1000); // Wait for 1000 millisecond(s)
  
  digitalWrite(13, LOW);
  Serial.println("Led Off");
  delay(1000); // Wait for 1000 millisecond(s)
}
