A 5V Active Alarm Buzzer 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 5V DC Electronic Part Active Buzzer Module. Using top-quality material, it is durable in use.

What is more, an 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. A good choice for you all!

Package Includes:

• 1 x 5V Active Alarm Buzzer Module for Arduino.
• 3 x F-F Jumper cable.

Features:

Passive buzzer features are:

1. Passive internal shocks without source- so if you can not make it with a DC signal tweet. Must be a square wave 2K ~ 5K to drive it
2. Sound frequency control- you can make a “more than a meter hair Suola” effect.
3. In some special cases- you can reuse a control and LED mouth

Active buzzer features are:

1. An active buzzer with a concussion internal source- so long as it will be called an energized
2. The program is easy to control- SCM can let a high-low sound- while the passive buzzer did not.

Module interface specification (3-wire)

1. + External 3.3V-5V voltage (can be directly connected with the 5v and 3.3v MCU MCU)
2. – External GND out external microcontroller IO port
