Piezo Buzzer Module with Transistor

This handy buzzer can be easily connected to an Arduino PWM output and generate a signal.   The buzzer is controlled on this module via a transistor, so you don't need to worry about the current carrying capacity of your microcontroller. The module can also be controlled with an ESP8266. The buzzer needs a PWM signal to control the frequency.
