Crowtail – Buzzer 2.0
The buzzer module is for making sound in your project. It sounds when activated by a logic HIGH signal. Connect the buzzer to any of the D (digital) ports of you can easily make it sounds with setting the related ports to logic HIGH. The buzzer module can be also connected to an analog pluse-width modulation (PWM) output to generate various of tones.
