Hi!
I got a buzzer for my project and it was not labeled what was its ohm so I'm confused what resistor to use for it 
Is there anyway I can find it?
Thank you 
Show us a link to where you bought it from?
Not sure what resistors have to do with this - it would have a specified operating voltage and would draw a certain amount of current, but this depends on what sort of buzzer it is.
Hi!
I bought the buzzers from here:

So where does that mention a buzzer?
Get a meter and measure the resistance of the buzzer. If you have not got a meter then get a meter.
it says it includes a buzzer in the description (which is down in the page)
And I don't have a meter and I don't want to get one because I will never use it
So is there anyway I can check the voltage without a meter?

You'll never need it!?!?
A multi meter is so useful to have around though . Testing bateries, checking for bad connections, fault finding for their price even a cheap one will be worth its weight in gold.
But till now I've never used it!
OK, so had to "allow" all sorts of Amazon links to get the description.
it is a piezo "buzzer/ speaker". It actually does not have a "resistance", it is effectively infinite.
You just connect it to the Arduino as directed in the exercises and use it. Generally a resistor is neither required nor relevant.
Never need a meter? Never need an oscilloscope, either. Until something goes wrong.

Til now you have never been working on Arduino projects either. A multimeter comes in handy for lots of jobs around the home, but it's invaluable if you're working in electric and electronic projects.

Your in the wrong hobby then.
Basic ones cost about $5 nowadays - and adequate for most purposes.
Very little of importance you can do in electronics without one.
There are at least three on the table in front of me. (That's the working ones - may be some more buried here - hard to tell.)

Good point. XD
