Active Speaker Buzzer Module for Arduino (Works with Official Arduino Boards)

Pros: Very simple to use. Very cheap. Small and somehow well made. Do what is proposed to do.

Cons: very annoying sound the pins are alocated in a not well designed position. due tue the fact that you propably going to use the buzzer with it's speaker up. it's pins configuration, it's not possible or at least make it difficult

Other: as I said, this is a very cheap component that sometimes is necessary to a project. it's very simple to use and connect. so, buy it if you need it

Pros: IT works fine, there are 3 connectors, +, - AND some kind of signal, based on the tension on this last one IT emits a different frequency. Standart connectors distance and very good price. Good loud, came with an little strip to close the sound exit, you must to remove it.

Cons: Like other arduino products should be with some kind of target naming the connectors this will make easyer to integrate this components in the project No one at all

Other: Right one for arduino projects

Pros: It seems to work the way it should. Simple to install and use! Great price!

Cons: The pin mapping is something I'm a little puzzled about; at first I couldn't get it working, but after a closer look at the connections it seems easier to connect GND to what is "S" on the buzzer and "-" to a PWM pin on the arduino.

Other: It works great, but take check the pins before use if you're uncertain!

Pros: Its a solid construction, came with a lot of protections in a sealed plastic bag, works really good on my arduino mega, works with computer output... and its a quite loud :D

Cons: dont have any datasheet... I dont know for what is the center pin (as it have 3 pins).

Other: Buy it if you want a good buzzer...
