Buzzer Setup in bolt

please send male female connections to buzzer ! also Can we connect buffer directly or we need ohm resistor like LED?

@ayusoun
Buzzer have same pins as that of LED. But it doesn’t require any resistor with it just put +ve pin that is the longer pin of buzzer to the any digital pin and -ve pin i.e. shorter pin to the ground.
you can vary sound of buzzer using analogWrite function.
