Piezo Buzzer

[n3ro]

Has someone tested a piezo-buzzer (or summer) with arduino?

i want to use THIS Buzzer for my low voltage sensor. But don't know if this is a matching component for arduino.

@n3ro That should work fine. You may want to add a resistor to limit current. Once you have one, I would measure actual current draw and see if a resistor is needed. Based on the specs provided, you should not need one, but you never know how accurate the specs are.

I've only tried this module so far for prototyping. Worked as intended using the default code. Haven't made any measurements on it. But it ran fine in a 3,3V circuit. Certainly loud enough. Some current limiting would probably not be a bad idea.

Edit: The module I have is of course passive. Not sure if that is what you want or not. Active vs Passive.
