Buzzer 10mm 5V VK10 Active

Description

Piezo buzzers are used for making beeps, tones, and alerts. This one is petite but loud! Drive it with a 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 drive’) for double the volume.
