Piezo Buzzer - PS1240


Piezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3-30V 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, but works quite well from 2KHz to 10KHz. 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.



netduino driver and netduino sample. This sample plays RTTL ring tones based on classic video games. They sound pretty good on a piezo buzzer or a small speaker.
