About this product
HW-508 is a 3-pin passive piezo buzzer module for Arduino and microcontroller projects. Because it is passive, it needs an external square-wave signal, such as a PWM output or the Arduino tone() function, to set the pitch. Typical uses include alarms, sound feedback and notification circuits.

How do I make it beep with an Arduino?
Connect the signal pin to a digital pin, the power pin to 5V and the ground pin to GND, then call tone(pin, frequency) in your sketch. Check the pin markings on your board before connecting.
Can it produce a sound with only a DC voltage applied?
No. A passive buzzer needs a changing signal to vibrate. Applying only a constant DC voltage will not produce a tone; an active buzzer is needed for that.
