Mini Active Buzzer

Works as a standard active buzzer or you can apply PWM to play tiny, bleepy tunes. Ahoy!

Connect a voltage (4-8v) to the pins to make Dumb Noise (tm) or use a PWM from a microcontroller to change the tones - check out this Tom's Hardware article for how to play tunes using a Raspberry Pi Pico!

It's got sturdy, labelled pins for connecting to jumper jerky or poking into a breadboard. The specs list the minimum voltage as 4V, but we found it worked fine with 3.3V from a microcontroller. Note that you need to connect it up with the right polarity for it to make noise, even if you're planning on going down the PWM route.

Pimoroni's service and support was up to its usual 5 star standard. In about 24 hours of placing the order for 5 Passive Buzzers, they arrived in the post, each buzzer in its own sealed poly bag clearly labeled Passive Buzzer. A quick test to satisfy a nagging doubt, showed that they were not the Passive Buzzers that I had ordered, but were, in fact, 5 Active Buzzers. As the Active and Passive Buzzers look virtually identical, it is easy to see how such a mistake could have happened.

Also works (if, perhaps, not so loudly) with a 3V supply (e.g. 2 x 1.5V cells or a CR2032 button cell etc.).
