If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

This piezo element needs some mass to make a loud noise or detect vibrations.
After I did that, it has a nice high pitched frequency range. It can also detect footsteps throughout my entire house with the standard Arduino ADC and no amplification. How awesome is that?

Nothing to add to the previous review - put some mass on (not a lot though) and it will detect slightest vibrations. Make sure it suits your application though.
