c++ - Arduino 中的正确声明语法

Question

我是 Arduino 的新手，我从 http://www.instructables.com/id/Arduino-Basics-Making-Sound/step2/Playing-A-Melody/ 借用了这段代码

当我尝试验证代码时，我得到了

error: expected declaration before '}' token

在最后一行。我该如何解决？同样，我是新手，所以如果您需要更多详细信息，请告诉我。

#include "pitch.h"

// notes in the melody:
int melody[] = {NOTE_C4, NOTE_G3,NOTE_G3, NOTE_A3, NOTE_G3,0, NOTE_B3, NOTE_C4};

// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
4, 8, 8, 4,4,4,4,4 };

  void setup() {
  // iterate over the notes of the melody:
    for (int thisNote = 0; thisNote < 8; thisNote++) {

    // to calculate the note duration, take one second
    // divided by the note type.
    //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
    int noteDuration = 1000/noteDurations[thisNote];
    tone(8, melody[thisNote],noteDuration);

    // to distinguish the notes, set a minimum time between them.
    // the note's duration + 30% seems to work well:
    int pauseBetweenNotes = noteDuration * 1.30;
    delay(pauseBetweenNotes);
    // stop the tone playing:
    noTone(8);
    }
  }

  void loop() {
  // no need to repeat the melody.
  }
}

您在代码末尾有一个无关的右大括号 }。删除最后一行中的那个，它不需要。
