Activity C3 — Digital outputs

Level 3 — Use two digital outputs at once

Complete the challenge

When you have done the copy and paste, your entire setup() function should look like this:

void setup() {
    pinMode(11, OUTPUT);    // set up pin 11 as an output.
    pinMode(11, OUTPUT);    // set up pin 12 as an output.
}

When you have changed the pin number, your entire setup() function should look like this:

void setup() {
    pinMode(11, OUTPUT);   // set up pin 11 as an output.
    pinMode(12, OUTPUT);   // set up pin 12 as an output.
}

When you have done the copy and paste, your entire loop() function should look like this:

void loop() {
    digitalWrite(11, HIGH);  // turn the LED on
    digitalWrite(11, HIGH);  // turn the LED on
    delay(100);              // wait for 1 tenth second
    digitalWrite(11, LOW);   // turn the LED off
    digitalWrite(11, LOW);   // turn the LED off
    delay(1000);             // wait for 1 second
}

When you have changed the pin numbers, your entire loop() function should look like this:

void loop() {
    digitalWrite(11, HIGH); // turn the LED on
    digitalWrite(12, HIGH); // turn the LED on
    delay(100);             // wait for 1 tenth second
    digitalWrite(11, LOW);  // turn the LED off
    digitalWrite(12, LOW);  // turn the LED off
    delay(1000);            // wait for 1 second
}
