  • Piezo Transducer - Mini 5V Buzzer (4000Hz) (piezo buzzer 5V)

    If you want to add beeps, tones or alerts to your Raspberry Pi project, you require a Piezo Buzzer! This mini transducer is small but loud, and can be driven with a 1-20V peak-to-peak square wave. To use, connect one pin to ground (either one) and the other pin to a square wave out from a timer or microcontroller. For the loudest tones, stay around 4 KHz. For extra loudness, you can connect both pins to a microcontroller and swap which pin is high or low ('differential drive') for double the volume.

    This one plops perfectly into a breadboard and has short legs, so can also easily be mounted on a PCB! Please Note. This item is externally driven, e.g. requires a microcontroller to produce a tone.
