void setup()
{
    pinMode(led, OUTPUT);
}
void loop()
{
    digitalWrite(led, HIGH); // set the LED on
    delay(2000);             // wait for a second
    digitalWrite(led, LOW);  // set the LED off
    delay(2000);             // wait for a second
}

Digital Temperature

int Led = 13;      // define LED Interface
int buttonpin = 3; // define the digital temperature sensor interface
int val; // define numeric variables val
void setup()
{
    pinMode(Led, OUTPUT);
    pinMode(buttonpin, INPUT);
}
void loop()
{
    val = digitalRead(buttonpin);
    if (val == HIGH)
    {
        digitalWrite(Led, HIGH);
    }
    else
    {
        digitalWrite(Led, LOW);
    }
