Purecrea Piezo buzzer active

This practical active buzzer can easily be connected to a digital Arduino output and generate a signal. It is often used where a keystroke or confirmation is to be signalled. As it is an active buzzer, it has a fixed frequency of approx. 2500Hz that it emits. The buzzer can also be operated with 3.3V, but be careful and check first if your output can deliver 15mA (do not connect directly to the ESP8266). The long pin on the buzzer is the + terminal and the short one is GND.
