To keep the code easier to read/more organized, we've created a function to hold the song we're composing called playSong(). If yes, we'll call a function we created to play a song, and if not noTone() will keep the buzzer from making noise. Here we'll use an if() statement to check if the button is pressed.

Next we'll learn how to trigger sounds with an input so they are not constantly playing. One drawback of this code is that the sounds never stop. Try using the tone() and noTone() functions to compose a simple song.
To make a pause or rest, we can use the noTone() function followed by a delay. At the top of the sketch we created variables for musical notes with the frequency in hertz. To make a note last a certain amount of time, we use a delay() in between notes. To make the notes, we give the tone function two pieces of information - the pin the buzzer is attached to and the frequency we want to play - tone(pin, frequency). Upload this code to your LilyPad Arduino and listen - the code plays a scale. Use noTone() to shut off the buzzer and delay to create a 'rest'
Use the tone() function to play each note in a scale Using the tone() function and setting variables for each note. This example code shows how to hook up a LilyPad Buzzer to play a simple song If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE.If you have not previously installed an Arduino library, please check out our installation guide. Note: This example assumes you are using the latest version of the Arduino IDE on your desktop.
