Buzzer question

[Joachim08]

Can i connect the following buzzer directly to the arduino board:

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.

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.

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.

Best regards,

Anyone that have a url to an buzzer type that works with 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.

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
