Let’s Upload Blink.ino

Let’s Upload Blink.ino

(Continuing after the Arduino IDE install is complete.)

  1. Use the USB-A to USB-B cable to connect your HERO XL’s matching USB port with your computer.
  2. Select our board in Arduino IDE (Tools -> Board -> Arduino AVR Boards -> Arduino Mega or Mega 2560)
  3. Select the Port connected to the HERO XL (Tools -> Board -> (selection that contains “(Arduino Mega or Mega 2560)”)
  4. Load example Blink sketch (File -> Examples -> 01.Basics -> Blink)
  5. Compile Blink (Sketch -> Verify/Compile)
    • Compiling converts our text commands into code that a microcontroller can execute
    • If errors are found they are reported and no code is generated
  6. Upload and execute sketch on HERO XL (Sketch -> Upload)
  7. Observe built-in LED blinks on for one second and then off for one second.
/*
  Blink
  Turns an LED on for one second, then off for one second, repeatedly.
  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
