Description:
A passive buzzer module is a digital transducer with a built-in DC power supply. It is widely used in computers, printers, copiers, alarms, electronic toys, car electronics, phones, timers, and other electronic projects that need alert sounds.
This module can be mounted on a PCB and can produce different sound tones depending on the input frequency. It can generate tones from 1.5 to 2.5 kHz by switching on and off at different frequencies using delays or PWM.
This module is ideal for adding sound to your project and is compatible with a pin pitch of 2.54mm. It works with microcontrollers such as Arduino. This module allows you to create a buzzer sound that can be changed over a range of frequencies for maximum effect.
