Happy Birthday Tune Using Circuit Playground

Here's how to play the Happy Birthday Melody on Adafruit's Arduino Compatible board Circuit Playground.

I needed something small to embed in a box for a birthday box surprise

Copy and Paste this code into the Arduino IDE then name the file cpBirthday

/*
Happy Birthday Song!
Modified to work with Adafruit's Circuit Playground 
To play the song just press the right button on the Circuit Playground
Thanks to Mike Barela for writing a guide for the Tone library for CP
His tutorial can be found here:

 */
 
#include 
#include "pitches.h"
// Melody notes:
int melody[]= {NOTE_G3, NOTE_G3, NOTE_A3, NOTE_G3, NOTE_C4, NOTE_B3,
NOTE_G3,NOTE_G3, NOTE_A3,NOTE_G3, NOTE_D4, NOTE_C4,
NOTE_G3, NOTE_G3, NOTE_G4,NOTE_E4,NOTE_C4, NOTE_B3, NOTE_A3,
NOTE_F4, NOTE_F4, NOTE_E4, NOTE_C4, NOTE_D4, NOTE_C4 };
// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = { 8,8,4,4,4,2,8,8,4,4,4,2,8,8,4,4,4,4,3,8,8,4,4,4,2 };
void setup() {
CircuitPlayground.begin();
  
}
void loop() { 
  
  if(CircuitPlayground.rightButton()) { 
    
    for (int thisNote = 0; thisNote < 26; thisNote++) {
      
            int noteDuration = 1000/noteDurations[thisNote];
             // to calculating note duration  (1 second divided by the note type)
             
             CircuitPlayground.playTone(melody[thisNote],noteDuration);
             // to distinguish the notes, set a minimum time between them.
             
             int pauseBetweenNotes = noteDuration * 1.60;
             delay(pauseBetweenNotes);
             noTone(8);
       }   
    }
  
 }

Next add a new tab and name that file pitches.h which is a list notes and their frequencies by Brett Hagman

-copy and paste the following into that file

-save it

Make sure you've added the support for the Circuit Playground as explained on this tutorial from Adafruit.

-Select the Adafruit Circuit PLayground under boards as well as its COM port

-Click upload

- I used a 3 x AAA Battery Holder with On/Off Switch and 2-Pin JST connector to provide power to the board

Feel free to tweak the code as you'd like .
