How do I connect this buzzer to an Arduino?
Connect the positive (+) pin to a digital output pin and the negative pin to GND, then set the pin HIGH to sound it. Since the listed current is under 30 mA, it can usually be driven directly, but confirm your board's per-pin limit.
Does an active buzzer need a PWM signal to make a tone?
No. An active buzzer has its own oscillator, so it sounds when DC voltage is applied. A passive buzzer, by contrast, needs a PWM or tone signal to produce a sound.
