.:Piezo Elements:.

To this point we have controlled light, motion, and

electrons. Let's tackle sound next. But sound is an

analog phenomena, how will our digital Arduino cope?

We will once again rely on its incredible speed which will let it

mimic analog behavior. To do this, we will attach a piezo element to one of the

Arduino's digital pins. A piezo element makes a clicking sound each time it is pulsed

with current. If we pulse it at the right frequency (for example 440 times a second to

make the note middle A) these clicks will run together to produce notes. Let's get to

experimenting with it and get your Arduino playing "Twinkle Twinkle Little Star".
