![### Arduino Melody Code Example
#### Description:
This Arduino sketch is designed to play a melody using a series of notes. The code utilizes the "pitches.h" header file to access predefined note constants.
#### Code Breakdown:
```cpp
#include "pitches.h"
// notes in the melody:
int melody[] = {
NOTE_C5, NOTE_D5, NOTE_E5, NOTE_F5, NOTE_G5, NOTE_A5, NOTE_B5, NOTE_C6
};
int duration = 500; // 500 milliseconds
void setup() {
}
void loop() {
for (int thisNote = 0; thisNote < 8; thisNote++) {
tone(8, melody[thisNote], duration);
delay(1000);
}
delay(2000);
}
```
#### Explanation:
1. **Include the 'pitches.h' library**:
- This library contains definitions for standard musical notes.
2. **Define the melody array**:
- `int melody[] = { NOTE_C5, NOTE_D5, NOTE_E5, NOTE_F5, NOTE_G5, NOTE_A5, NOTE_B5, NOTE_C6 };`
- This array holds the notes of the melody, each note corresponding to a constant defined in "pitches.h".
3. **Set the duration of each note**:
- `int duration = 500; // 500 milliseconds`
- This sets a constant duration of 500 milliseconds for each note.
4. **Empty setup() function**:
- `void setup() {}`
- The setup function is kept empty as no initialization is required for this specific sketch.
5. **Loop through the melody**:
- `void loop() { for (int thisNote = 0; thisNote < 8; thisNote++) { tone(8, melody[thisNote], duration); delay(1000); } delay(2000); }`
- The `loop()` function plays each note in the melody using the `tone()` function.
- The `tone()` function is called with three parameters: the pin number (8), the note frequency, and the duration.
- After each note, the `delay(1000);` function pauses the program for 1 second.
- Once all notes in the array are played, the `delay(2000);` function pauses the program for 2 seconds before](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6e366a85-c23b-450a-9bc7-d2ea0be52d3f%2F50660ceb-c702-44dd-829c-d80b1a05470c%2Frax8qy_processed.png&w=3840&q=75)
