Tasks 21, 22 and 23

Task 21:

int del = 200;
int LEDPin = 13;
void setup()
{
  Serial.begin(9600);
  pinMode(LEDPin, OUTPUT);
}

void loop()
{
  digitalWrite(LEDPin, HIGH);
  Serial.println("Blink");
  delay(del);
  digitalWrite(LEDPin, LOW);
  delay(del);
}


Task: 22

int del = 200;
int LEDPin2 = 2;
int LEDPin3 = 3;
void setup()
{
  Serial.begin(9600);
  pinMode(LEDPin2, OUTPUT);     
  pinMode(LEDPin3, OUTPUT);
}

void loop()
{
  digitalWrite(LEDPin2, HIGH);  
  Serial.write("Red ");
  delay(del);                 
  digitalWrite(LEDPin2, LOW);
  delay(del);

  digitalWrite(LEDPin3, HIGH);
  Serial.print("Yellow");
  delay(del);
  digitalWrite(LEDPin3, LOW);
  delay(del);
  Serial.println();
}


Task 23:

I was unable to edit the Wikieducator page so i shall just show my version of the Arduino here.
