Arduino Blink

This is a very simple starter program for Arduino beginners. It is commonly called blink. It does what the title says it does: it makes a LED (any color) blink!
Materials you will need:
Arduino (I have the Uno, and am using it)
Connection cord (From Arduino to computer)
LED (Mine is red)

Connect connecting cord to port on Arduino, then to computers USB port.
Code
Here is the code For the program. Put it into your Arduino program.
int led = 13;
void setup() {
pinMode(led, OUTPUT);
}
void loop() {
digitalWrite(led, HIGH);
delay(1000);
digitalWrite(led, LOW);
delay(1000);
}
int led = 13;
void setup() {
pinMode(led, OUTPUT);
}
void loop() {
digitalWrite(led, HIGH);
delay(1000);
digitalWrite(led, LOW);
delay(1000);
}

Plug the LED into the 13 pin on the digital side, and the other leg into ground. If everything goes right, the LED will blink on and off!
Note: Some Arduino models have a built in LED on the board.
