Passive Buzzer Module for Arduino/AVR/PIC - Tone Output dfr0423 The current's polarity determines whichThis passive buzzer is one loud noisemaker. Unlike active buzzers and plain piezos, this buzzer does not need an oscillating signal to create sound. That is why it will automatically screech a 2KHz beep when applied to a 3 5V input voltage. Specifications: Input voltage: 3 5V Size: 26 x 15 x 10mm Library: None Inclusions: 1 x Passive Buzzer Module for Arduino AVR PIC Documents: None
