Active Piezo Buzzer Module
Requires 5v to operate - For Arduino circuits

This listing is for a small active piezo buzzer modules.  When you apply 5v to this module, and you drive the signal (I/O) line low, the on board buzzer activates.  It is extremely easy to use, and there is a demonstration video below that acts to show you how it works.  There are three pins on the board, and it comes with a three-wire connector for easy interface with your arduino.  The supply and interface pins are labelled on the board, and are talked about below.  If after you watch the video you still have questions, please feel free to send us a question, and we'll get back to you ASAP!

Interface Pins:
VCC - Supply line.  Connect 5v here.
GND - DC ground line
I/O - Input trigger.  When this line is driven low (0v/GND),the buzzer activates.
