I feel rather stupid to even be asking this... It came with a kit I got a while ago, I believe it to be a microphone. Can anyone specify?

 

Could be a piezo buzzer, too.

 

I believe it to be a microphone.

...Either that or a small piezo speaker

Did the kit, perchance, feature an ultrasonic range-finder? -- It's about the right size for a low-power ultrasound transducer...

... or both, a piezo transducer... can be used as a microphone or a buzzer.

 

What is the kit for? That might give a clue.

Does the kit not have a parts list?

 

Everything was taken out when I organized my stuff a while back. It was a kit with an aruino uno. I do recall 2 stepper motors that also came with it. No range finder(that im used to seeing) as far as I can remember, but I might be wrong about that. Don't have the parts list either.

If it was a robot it may have featured a range finder for obstacle detection? -- Just a thought

Measure its resistance, I'm guessing it's a tiny moving coil loudspeaker.

Measures at 7.1 ohms

 

Suspiciously close to 8 Ω -- a moving coil speaker (don't know about the 'loud' part of it) is sounding (no pun intended) more likely.

 

A lot of the kits include a force sensor, but those have a high resistance when not under pressure.

 

It's a small speaker no doubt ...
