SeeedStudio Grove Buzzer

• This Grove – Buzzer v1.2 module has a piezo buzzer as its main component. The piezo element makes a clicking sound each time when it is pulsed with current. If we pulse it at the right frequency (for example, 440 times per second to make the note middle A), these frequent clicks will run together to produce a little melody.
• You can use this Grove – Buzzer as an audio element, a sound notification, an alarm, or even a little tune! You can use it for various purposes. This buzzer is a great way to indicate something is happening with your GrovePi or GoPiGo robot car! Connect this buzzer to digital outputs, and you’ll hear a tone when the output gets high. Alternatively, you can connect it to an analog pulse-width modulation output to generate various tones and effects.
