BUZZER MODULE Digital Buzzer Module DC 3.3V 5V 3Pin Active Passive Buzzer Circuit Low Current Buzzer Alarm Sound Module For Arduino Electronics

This buzzer module can be used to build alarm/doorbell DIY circuits. It’s useful whenever you need audio feedback in a project. Passive buzzer is a device you have to send it an AC sound signal and you can control the sound. The arduino needs to generate the tone. With enough hardware and software you can make it play music. The only downside ( besides a bit of extra programming) is that it takes processor-time to generate the sound. This could be an issue if your program is doing lots of other thing at the same time. A piezo speaker can be driven directly from the arduino.

A High Current Active Alarm Buzzer Driver Module 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’s more? This 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!

Features:

• This active buzzer has an internal oscillation source, so it alarms while energizing.
• Convenient program control, a high and low level single chip microcomputer can make it sound better than a passive buzzer.
• Module is powered with 9012 transistor.
