Hot line bling ardino help

Processing Electronics (Arduino, etc.)

I am supposed to get the below code or create a code that play hot line bling by Drake but i don’t understand how to input the notes for it.

 /******************************************************************

const int buzzerPin = 9;    // connect the buzzer to pin 9
const int songLength = 18;  // sets the number of notes of the song

// Notes is an array of text characters corresponding to the notes
// in your song. A space represents a rest (no tone)

char notes[songLength] = {
  'c', 'd', 'f', 'd', 'a', ' ', 'a', 'g', ' ', 'c', 'd', 'f', 'd', 'g', ' ', 'g', 'f', ' '}; 

// beats[] is an array of values for each note. A "1" represents a quarter-note, 
// "2" a half-note, and "4" a quarter-note.
// Don't forget that the rests (spaces) need a length as well.

int beats[songLength] = {
  1, 1, 1, 1, 1, 1, 4, 4, 2, 1, 1, 1, 1, 1, 1, 4, 4, 2};

int tempo = 113;  // The tempo is how fast to play the song (beats per second).

void setup() 
{
  pinMode(buzzerPin, OUTPUT);  // sets the  buzzer pin as an OUTPUT
}


void loop() 
{
  int i, duration; //

  for (i = 0; i < songLength; i++) // for loop is used to index through the arrays
  {
    duration = beats[i] * tempo;  // length of note/rest in ms

    if (notes[i] == ' ')          // is this a rest? 
      delay(duration);            // then pause for a moment
    else                          // otherwise, play the note
    {
      tone(buzzerPin, frequency(notes[i]), duration);
      delay(duration);            // wait for tone to finish
    }
    delay(tempo/10);              // brief pause between notes
  }

  while(true){
  // We only want to play the song once, so we pause forever
  }
  // If you'd like your song to play over and over, remove the while(true)
  // statement above
}

int frequency(char note) 
{
  int i;
  const int numNotes = 8;  // number of notes we're storing
  char names[numNotes] = { 
    'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C'    };
  int frequencies[numNotes] = {
    262, 294, 330, 349, 392, 440, 494, 523    };

  // Now we'll search through the letters in the array, and if
  // we find it, we'll return the frequency for that note.

  for (i = 0; i < numNotes; i++)  // Step through the notes
  {
    if (names[i] == note)         // Is this the one?
    {
      return(frequencies[i]);     // Yes! Return the frequency and exit function.
    }
  }
  return(0);  // We looked through everything and didn't find it,
  // but we still need to return a value, so return 0.

  • please tell us in how far that is a processing question.

  • it is an arduino example code:

    • did you load it up successful to a arduino?
    • does it play a sound when you correct wired hardware?
    • did you change the notes in the array “notes” to generate a different song?

It loaded up successfully and it played a sound when i wired it correctly but i didn’t know how to change the notes is why i asked for help .

Edit these two variables:

// Notes is an array of text characters corresponding to the notes
// in your song. A space represents a rest (no tone)

char notes[songLength] = {
  'c', 'd', 'f', 'd', 'a', ' ', 'a', 'g', ' ', 'c', 'd', 'f', 'd', 'g', ' ', 'g', 'f', ' '}; 

// beats[] is an array of values for each note. A "1" represents a quarter-note, 
// "2" a half-note, and "4" a quarter-note.
// Don't forget that the rests (spaces) need a length as well.

int beats[songLength] = {
  1, 1, 1, 1, 1, 1, 4, 4, 2, 1, 1, 1, 1, 1, 1, 4, 4, 2};

So for example:

433×960 69.1 KB

then

char notes[songLength] = {
  'c', 'c', 'g', 'g', 'a', 'a', 'a', 'g', ' ', 'f', 'f', 'e', 'e', 'd', 'd', 'c', ' '}; 
int beats[songLength] = {
  1, 1, 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 1, 2};

where could i get the notes for hotline bling?

I don’t know. Maybe google searching the song name, plus “notes” or “sheet music” or “tabs” or “melody” or “for guitar” or “for piano”, or “how to play”…?
