In this experiment, we will learn how to use buzzer module.
With the Arduino we can complete a lot of interactive work, commonly what we used is the
light shows. And we has been use the LED small lights in the experiment before. In this
experiment we will make the circuit having noise. The common components that can
make sound are buzzer and speakers. Compared to the speaker, buzzer is more simple
and easy to use so in this experiment we adopts the buzzer.
