Tasks 13-16(Complete except 16)

13. Write a program that will have the LED mostly off. That is it only blips on once a second if you look closely.

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://arduino.cc

  This example code is in the public domain.

// 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() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(100);              // wait for bit
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(900);              // wait for rest of a second
}

14. Same as 13 but this time have your LED mostly on.

15. Repeat 14 with an external LED on a breadboard.
Done, same code

16. Copy the two LED program into your blog and run it.
 WHERE is it?
