Part Name: Adafruit $0.2W$ $8\Omega$ Mini Speaker

Part Description: A speaker is a device that emits audible sound waves in response to an electrical audio signal. The electrical signal usually needs to be amplified by an audio amplifier to some degree before being transmitted out of the speaker. The mini loudspeaker in your kit is rated at $0.2W$, which determines the volume level capacity. Be careful not to supply too much power to the speaker to avoid blowing it out!
