3v piezo buzzer module for arduino

This listing is for a neat little piezo buzzer module. If you apply three volts, it will output sets of four beeps consecutively. There is a short delay between each set of four beeps. It acts as a warning. It is easily interfaced with any microprocessor, but was designed for arduino. SEE THE VIDEO BELOW FOR A DEMONSTRATION. It is very easy to use. If you use 5v on this circuit, you won't damage it, but it will not work correctly.
