Buzzer to run off batteries

Support Product Questions
1

Hi I run a STEM centre at our school. I have previously purchased some buzzers with the intent of using them with batteries only but it seems the ones I bought require a microcontroller or similar in order to operate, from my research these are passive buzzers. I have had trouble finding options for active buzzers on the website, ones that can be run in projects with batteries wires and switches only. If you could point me in the right direction that would be great

Hi Shane
I think most of Core offerings have to be driven with a square wave or something like that.
Jaycar seem to have a selection of buzzers with built in drive circuits. In other words they will “self buzz” with the application of a DC voltage.
Search “Buzzer” on the Jaycar page.
Cheers Bob

Thanks Bob

I thought I might have to go elsewhere, tried to avoid it since we have been using core electronics exclusively for a while now but I will look into it, thank

Hi, I had a look at that one just then, seems it has to be driven with a square wave like I think the other ones I am trying to use are, thanks for the help

Hi Shane,

It might be worth an email, I recall them stocking a similar buzzer to this:Piezo Buzzer | Buy in Australia | CE09240 | Core Electronics

But an active version, is that kind of what you are after?

Ah I understand what you mean now by active and passive. Sorry I misunderstood.
