  Second Iteration: Cocoon 

   

  

  Code:

  void setup();
  void loop();
  int timer = 500;                   // The higher the number, the slower the timing.
  int pins[] = { 5, 7, 8, 10 }; //  pin numbers
  int num_rows = 4;                  // the number of pins

  void setup()
  {
    int i;

    for (i = 0; i < num_rows; i++)   // the array elements are numbered from 0 to num_pins – 1
      pinMode(pins[i], OUTPUT);      // set each pin as an output
  }

  void loop()
  {
    digitalWrite(pins[0], HIGH);
    digitalWrite(pins[1], HIGH);
    digitalWrite(pins[2], HIGH);
    digitalWrite(pins[3], HIGH);
   
    delay(2000);
   
    int i;
    int j;
    int height = 4;
   
     for (i = 0; i < num_rows; i++) { // loop through each row…
       digitalWrite(pins[i], LOW);
       delay(timer);
       for (j = height; j > 0; j–) {
         digitalWrite(pins[i], HIGH);   
         delay(timer);
         digitalWrite(pins[i], LOW);
         delay(timer);
       }
       height–;
       delay(timer);
     }

  }
