Is the LED lesson a bit too complex?

Hi Gareth, I wonder if this is a bit too complex for a one hour lesson. There is a lot to learn in terms of putting together the circuit and the programming. My first attempt with LEDs from the Arduino had just one LED (the Blink lesson) and then I built it up to three. When I showed Blink to Roisin, she wanted to change the LED and change the frequency of the lights. I let her do this, of course. Learning how to put stuff into the breadboard takes a bit of practice. I guess this can all be evaluated this afternoon. Just my thoughts... Best wishes, Paul P.S. here is my simple sketch...

/*

 */

// name the pins that we've connected to our LED
int red = 14;
int yel = 10;
int grn = 9;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pins as an output.
  pinMode(red, OUTPUT); 
  pinMode(yel, OUTPUT);
  pinMode(grn, OUTPUT);  
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(red, HIGH);   // turns red LED on (HIGH is the voltage level)
  digitalWrite(yel, LOW);
  digitalWrite(grn, LOW);  
  delay(2000);               // wait for two second

  digitalWrite(yel, HIGH);    // turn the yellow LED on by making the voltage HIGH
  delay(500);               // wait for half second

  digitalWrite(red, LOW);   // turn the red LED off (LOW is the voltage level)
  digitalWrite(yel, LOW);
  digitalWrite(grn, HIGH);
  delay(2000);               // wait for two second

  digitalWrite(yel, HIGH );    // turn the LED on by making the voltage HIGH
  digitalWrite(grn, LOW);
  delay(250);

}
