Name |  | ### delay()
Examples |  |
    int pin = 0;
    int ledpin = 1;

    void setup() {
      pinMode(pin, INPUT);
      pinMode(ledpin, OUTPUT);
    }
    void loop() {
      if(pin == HIGH) {
        digitalWrite(ledpin, HIGH);
      } else {
        digitalWrite(ledpin, LOW);
      }
      delay(250);  // Stops the program for 250 milliseconds
    }
