It is easy to generate sounds with Arduino using the tone function:
tone(pin, frequency, duration)
You can make a sequence of notes to play a melody.
But this function is limited to play one note per time, so we can’t play more complex musics.
To address this issue, we’ll use the Len Shustek’s PlayTune library.
This library is capable of playing up to 6 tones simultaneously (3 using Arduino Uno and 6 using Arduino Mega).”
