Buzzer Setup in bolt

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

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.
