Passive Buzzer(SE044)

1 Introduction

This module is similar with the Active Buzzer, the only difference is that this module

only can be driven square wave signal, not DC signal.

2 pinout

Description

Signal input pin, which can be driven by

square wave signal

Power(3.3V/5V), you may not see this

mark on the board, it’s the middle pin

Ground

3 Example

Here is a example that driven the Passive buzzer sound. The connection as below:

IDUINO for maker’s life connect straight to the Arduino Mini, Arduino Ethernet or other microcontrollers, allowing them to talk to the computer. One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and IO level). This board ship default to 5V, but you can cut the default trace and add a solder jumper if you need to switch to 3.3V.
