An Active Buzzer Alarm Module for Arduino is an audio signaling device, which may be mechanical, electromechanical, or piezoelectric. Just like what you are viewing now, it is a 3.3V-5V DC Electronic Part Active Buzzer Module. Using top-quality material, it is durable in use.
An 5V active buzzer rings out as long as it is electrified. Compared with a passive buzzer, it is a bit expensive but easier to control. Typical uses of buzzers include alarm devices, timers, and confirmation of user input such as a mouse click or keystroke.
Module Interface Specification (3-wire)
+ External 3.3V-5V voltage (can be directly connected with the 5v and 3.3v MCU MCU)
– External GND out external microcontroller IO port.
Applications:
- The 5V buzzer can be used in making Fire Alarm using Arduino
- Security System
- Audio signaling device
- Alarm
- Timers
