Key Functionality

This passive piezoelectric buzzer module produces audible tones within a frequency range of 1.5 to 2.5 kHz. The sound is generated by switching the buzzer on and off at different frequencies, which can be easily controlled via simple delay loops or Pulse Width Modulation (PWM) from a microcontroller.
