## delay(ms)

#### Description

Pauses your program for the amount of time (in miliseconds) specified as parameter.

#### Parameters

ms: the number of milliseconds to pause (there are 1000 milliseconds in a second)

#### Returns

nothing

#### Example

    int ledPin = 13;                 // LED connected to digital pin 13

    void setup()
    {
      pinMode(ledPin, OUTPUT);      // sets the digital pin as output
    }

    void loop()
    {
      digitalWrite(ledPin, HIGH);   // sets the LED on
      delay(1000);                  // waits for a second
      digitalWrite(ledPin, LOW);    // sets the LED off
      delay(1000);                  // waits for a second
    }

configures pin number 13 to work as an output pin. It sets the pin to HIGH, waits for 1000 miliseconds (1 second), sets it back to LOW and waits for 1000 miliseconds.
