Melody

This is a small and straightforward library to play melodies through a buzzer on Arduino.

The starting point to this library was ToneMelody, I used the codes from there. Just made it a bit easier to use.

Install

I uses the the ArduinoSTL library, so before use you need to install it.

Usage

The libary comes with the Note and Melody class and some constants to make it easier to compose.

NOTE

Note is helper class to define the notes and their length in the melody.

It has one contructor which accept two ints, one for the frequency and one for their length (1/4, 1/8, etc.)

Note note(NOTE_C4, 4);

The 4 up there is for the 1/4 length

Melody

It has only a default constructor, and has three methods:

1. void attach(int): Attach the pin with the buzzer on it.
2. void addNote(Note): Add a Note to the end of your melody.
3. void play(): Play your melody.
4. void play(int): Play your melody on selected pin.

Example

The example below does exactly the same as the code in TomeMelody

#include <melody.h>

const int twitter = 5;
Melody melody;

void setup() {
    melody.attach(twitter);

    melody.addNote(Note(NOTE_C4,    4));
    melody.addNote(Note(NOTE_G3,    8));
    melody.addNote(Note(NOTE_G3,    8));
    melody.addNote(Note(NOTE_A3,    4));
    melody.addNote(Note(NOTE_G3,    4));
    melody.addNote(Note(NOTE_PAUSE, 4));
    melody.addNote(Note(NOTE_B3,    4));
    melody.addNote(Note(NOTE_C4,    4));

    melody.play();
}

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