I was wondering how loud the buzzer was meant to be. With volume=2 in a quiet room it is barely audible.

Hi Fractal,

They arent a suuper loud buzzer but the frequency that you are trying to play also influences how loud it seems, a couple in harmony start to get lound.

I’ve also found if you have some plastic or paper cups around popping the buzzers inside of them make it a tad louder (provided theyre pointed at you).

Hi Liam120347

Thanks for your reply. I did try different frequencies and found it was loudest at around 3000Hz. Perhaps using loud is the wrong word because to hear any sound from the board at all I have to wait until it is quiet, close the door and move my ear very close to it.  
I have checked the library is up to date and the python scripts run without error. Cannot think of anything else I can do to fault find. Perhaps the board is faulty.

Hey Fractal,

It’s odd that you have to get sooo close, as mentioned before they arent super loud like the speaker from your phone. All up the buzzer outputs \<0.015W.  
Check out the Core tutorial for a quick reference and a project I made:

- [PiicoDev Buzzer | Raspberry Pi Pico Guide - YouTube](https://youtu.be/bJVNKOmJQM8)
- [BuzzBox demo - YouTube](https://youtu.be/z7UbgZcqoIo)

All of them are tested prior to being shipped so the chance of it being faulty are slim (but not impossible) -it’d be worth sending through a video of it working.

There isnt a massive amount of power to work with on the I2C bus, its also using the raw GPIO to drive the buzzer which is very interesting.

Hi there,  
Is there an Arduino library for these guys? I bought a couple and just assumed there would be 😬

Thanks,  
Paul

Hi Paul,

At the moment there is only Micropython/Python libraries for the Buzzer module but all of the code is open-source so if you’re keen on getting your hands dirty. Its also likely that you can strip away all of the other functions you don’t need.

I’m curious though - why Arduino instead of Micropython?

Hey Liam,  
Thanks for responding so quick!  
Yeah I would love to make an Arduino library for it but have sooooo many other fun tasks to do if you know what I mean. I’m building an ocean going autonomous boat, and its a project that just keeps getting deeper and deeper, pardon the pun. But good fun that’s for sure and that’s the point.  
I prefer C/C++ to Python, really just because that’s what I know I guess. And now I have so much time invested in it it would be a big change to switch. Maybe one day.  
I use PlatformIO rather than the Arduino IDE, VSCode/PlatformIO is so much better than the Arduino IDE once you get deep in C/C++ stuff on Arduino.  
thanks,  
PJ

Hi Jeff,

No worries! Oooh yeah, I imagine just about everyone on the forum is neck-deep in projects!

Fair call! Pythononic languages cut down dev time a lot so if you’re ever keen to learn its worth it 100%.

Old post, but I have to agree, the buzzer is very quiet. I too have to put it up to my ear to hear it, although it helps if I hold it with the chip facing my palm.
