This device will generate a tone using an internal oscillator, so all that is needed is a DC voltage.
Description:
The active buzzer has a shock source inside, so it will be called as long as it is electrified. Program control is convenient. 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 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.
This is a active buzzer so its easy in use. You just apply voltage to the buzzer and it makes sound. Disadvantage is that you can’t determine the frequency of the sounds, for this you need a passive buzzer.
