Examples |  |
    int data = 0; // Wiring pin 0 for data
    int clock = 1;  // Wiring pin 1 for clock
    int strobe = 2;  // Wiring pin 2 for the strobe (latch)
    byte counter = 0;

    void setup() {
      pinMode(data OUTPUT);
      pinMode(clock, OUTPUT);
      pinMode(strobe, OUTPUT);
    }

    void loop() {
      digitalWrite(strobe, LOW);
      shiftOut(data, clock, MSBFIRST, counter);  // writes counter to the register
      digitalWrite(strobe, HIGH);
      delay(1000);
      counter = counter + 1;
    }
