Servo + Som

Aqui simplesmente peguei um código que prometia fazer o servo tocara a marcha imperial (e consegue, mas bem baixo) e como percebi que era basicamente um código normal de música troquei o servo por um buzzer e depois coloquei o servo pra ficar indo e voltando de um ângulo arbitrário no mesmo passo da música
