Micro electronics, trying to find a waling buzzer

[Lisapete]

Trying to find a buzzer that goes on and off rather than just on all the time. Needs to run off 9v battery. No idea what this part is refereed too official. Anyone able to point me in the right direction

As in periodic on.off.on.off or a single tone then silence?

As opposed to the moaning buzzers which are called rabbits IIRC

Ha!

Maplin sell two tone buzzers for about £5. I would assume they have the on/off/repeat version as well. Is it called "pulsed buzzer"? If so maplins 3 tone buzzer should do it for you.

You could try a TEC3M reverse buzzer used to show bulb failure in cars when towing.

A simple wailing sound can be generated with a small motor in the circuit with a speaker - Basically a air raid siren effect.

Yeah...but do you really want to create a spinning speaker?!

Are you making an 'everything is ok' alarm?

Those continuous bongs in nuclear power stations are creepy.

Pulsing alarm at how many bpm would be helpfull.

Thanks will give it a try

It's alarm to alert you the pad/circuit is armed
