Question.7

Jerry wants to control an LED connected to pin 13 on his Arduino Uno. He wants to make the following pattern on LED, in a loop

Which of the following codes will accomplish this?

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, LOW);
  delay(1000);
  digitalWrite(13, HIGH);
  delay(100);
}

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);
  delay(1000);
  digitalWrite(13, LOW);
  delay(100);
}

void setup() {
pinMode(13, OUTPUT);
}

void loop() {
digitalWrite(13, 1);
delay(100);
digitalWrite(13, 0);
delay(1000);
}

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);
  delay(100);
  digitalWrite(13, LOW);
  delay(1000);
}
