Test code to use 3 pins and debug.
// the setup function runs once when you press reset or power the board
void setup() {
  Serial.begin(115200);

  pinMode(0, OUTPUT);
  // Disable to use TX pin for Serial debug
//  pinMode(1, OUTPUT);
  pinMode(2, OUTPUT);
  pinMode(3, OUTPUT);
}

byte i = 0;
// the loop function runs over and over again forever
void loop() {
  Serial.print(F("Led to blink --> "));
  Serial.println(i);

  digitalWrite(i, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(i, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second

  i++;
  // Skip TX pin
  if (i==1) i++;
  if (i>3) i=0;
}
