How to see if the Arduino M0 Pro is working?

Hey guys,

I have here an Arduino M0 Pro and I think it is not working. I already tried some projects with online tutorials, but none of them worked.

To give you an example, I tried the "blink example" that comes with arduino IDE, but nothing happened.

Here is the code:

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an 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

Plus, in the attachments you can see the arduino that I am using.

Is there another way to test it so that I can see if it works or not?

Thank you for your time,
