Lesson 2 – code example blinking LED

This is Code to Lesson 2 – Blinking Leds (on board LED)

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  for (int i=1;i<10;i++)
  {
      digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
      delay(1000);              // wait for a second
      digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
      delay(1000);  
  }  // wait for a second 10 times
  for (int i=1;i<10;i++)
  {
      digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
      delay(100);              // wait for a second
      digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
      delay(100);  
  }  // wait for a  0.1 second 10 times  
}
