A buzzer is nothing but an electronic device that is used to play tones In our example we are plugging the buzzer on the pin number 9, that supports the functionality of writing a PWM signal to it, and not just a plain HIGH or LOW value.The first example of the code will just send ...

a tone when the output is high. Alternatively, it can be connected to an analog pulse-width modulation output to generate various tones and effects. If you would like to connect Grove - Buzzer as well as other Grove modules to Arduino boards, we recommendGrove Base Shield V2.0 for Arduino...
