Thanks fungus,

I think I understand now. Basically the buzzer needs a voltage switched on and off very quickly. Looking at the Jaycar page for the buzzer it is rated at 6-14VDC. So, it needs more voltage than the arduino can supply, right? Actually I wanted to get this component:

It is rated at 3-16VDC, so might this work? It wasn't in stock, so I ended up with this:

Thanks again, fungus. :-)

The ones I've seen switch it on and off themselves, internally.

You just apply a constant voltage and they buzz.

That one should work, yes. Voltas and amps are within Arduino range.


Thanks again, fungus. :-)

No, I don't answer questions sent in private messages (but I do accept thank-you notes...)

This buzzer has a fixed noise frequency,   which means it will generate that sound frequency itself  if you simply apply a sufficient voltage.

You don't have to generate any oscillating voltage yourself to drive it.
