Pinout for the Geekcreit passive buzzer module from the Geekcreit 37 in 1 sensor module board set kit for Arduino.
Below is an image showing the pinout of the passive buzzer module. The middle pin is not connected. The left pin connects to the positive (+) pin of the buzzer and the right pin connects to the negative (-) pin of the buzzer.
Typically the positive pin will connect to an I/O pin in an Arduino circuit and the negative pin will be connected to an Arduino GND pin. The middle N.C. pin is left unconnected.
The buzzer module is passive because it does not have any internal electronics to generate a sound or tone. External electronics or a microcontroller based device, such as an Arduino, is needed to make the device produce a sound.
Because the device is passive, it acts more like a tiny loudspeaker than a buzzer. It can be used with the Arduino toneMelody example sketch found in the Arduino IDE under File → Examples → 02.Digital → toneMelody.
The passive buzzer module tutorial shows basic use and testing of the passive buzzer module with Arduino.
