/*
  Blink Entire Row
  Turns on an LED on for 200 milliseconds, then turns on next LED.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://www.arduino.cc

  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize all digital pins as output pins. - pins 1 to 13
  for (int i = 1; i<14; i = i + 1){
    pinMode(i, OUTPUT);  
  }
  
}

// the loop function runs over and over again forever
void loop() {
  //turn on each led in turn
  for(int i = 1; i<14; i = i + 1){
    digitalWrite(i, HIGH);   // turn the LED on (HIGH is the voltage level)
    delay(200);              // wait for a 200 milliseconds
    digitalWrite(i, LOW);    // turn the LED off by making the voltage LOW
