5V Buzzer (Pack of 2) 10P The module featuresPiezo buzzers are used for making beeps, tones and alerts. This one is petite but loud! Drive it with 3 5V 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
