Can i connect the following buzzer directly to the arduino board:
http://www.emartee.com/product/41835/Mini%20Buzzer
Maximum current will be 30 mA.
The question now is where to connect the buzzer to ?
I assume i need an additional buzzer.pde which i have downloaded
from the multiwiii svn.

Re: Buzzer question
For Pro Mini DC Current per I/O Pin = 40 mA
It should work..
But place a resistor in series to reduce the currant a little.

Hello,
To me it looks like the buzzer needs to be fed with a frequency signal, not DC. if this is so then it will not work.
Useful looking little board but not for feeding from the buzzer output without software modification.

Re: Buzzer question
Hi all,
I have the same problem. I have purchase a buzzer like that but it doesn't not work with the software, because it seems to be feed by a frequency signal, and the multiwii software doesn't do that.
Does anyone have a sample code of how to use this kind of buffer? Or, what kind of buzzer do I have to use in order to work with the standard software?
Thanks in advance.

Hi,
I use a buzzer with an integrated driver KPX-G1205AL-K75 and it works perfect with the default code.

I would also be interested in this. At least what kind of buzzer, I guess it should be quite a loud buzzer too.
Will it be enough to connect it in series with a resistor or do I need a driver of some kind? This is for connecting to D8 on a Pro Mini (5V).
Regards.

This is circuit and Buzzer I use. Easy and very low cost to build.

Thanks mate, this is just what I needed.
Re: Buzzer question
I can confirm that my hobbyking buzzer (active one) with rc signal works actually with MW 2.2
when the first alarm appears i got : a long beep following by 5 litlle one and finish with a long. is it the correct behavior ???? who knows ?
I will try today with a passive buzzer (just the piezo) to see if i have the same bip. ciao
