CurieBot loves to sing! You can have her drive up and serenade someone by adding a piezo buzzer and some software.

Open the Ada_CurieBot_RC_Song sketch in the Arduino IDE and upload it to your robot.

In this code snippet you can see how you'll use the tone() command to make music. The melody[] array and noteDurations[] array are used to describe the pitch and time value of each note. 

CurieBot will play "Shave and a Haircut" by default, but you can change the song to anything you like, or even add other tunes, each one controlled by a different number on the Bluefruit LE app.

      if (buttnum == 2){
        int melody[] = {262, 196, 196, 220, 196, 0, 245, 262 };
        int noteDurations[] = { 4,8,8,4,4,4,4,4 };
        for (int thisNote=0; thisNote < 8; thisNote++){
          int noteDuration = 1000 / noteDurations[thisNote];
          tone(12, melody[thisNote], noteDuration);
          int pauseBetweenNotes = noteDuration * 1.30;

Now, use the Bluefruit LE app to drive CurieBot, and then whenever you press the "2" button, CurieBot will play a song!

Now that you've built your own robot friend, what kinds of modifications to hardware and software will you make next?
