We're almost there!!!!!!!!!!

So our code is almost complete! We're getting a better idea on how/ when to use the "if" and the "While" and realized that they were not being used properly for the function we are looking to have in our last code. We've switched things around, rewrote much of the "Void Loop" and also organizing elements by providing our own names for different variables, such as "brushlight".

// notes in the melody:
int melody[] = {
  NOTE_C4, NOTE_G3,NOTE_G3, NOTE_A3, NOTE_G3,0, NOTE_B3, NOTE_C4};
