The KY–006 passive piezo buzzer is a 3-pin module that creates an audible sound of varying frequencies using pulse width modulation (PWM). It can produce a range of tones and sounds depending on the input. Due to this, it is commonly used to create sound effects or simple musical notes for short songs.
