How to do the Buzzer project

How to do the buzzer project…? I am not getting it.

I guess u have used resistor for buzzer
In this project u should not use resistor

Circuit connection
Connect long pin of buzzer to 0
And connect short pin of buzzer to GND

Note
Do not use resistor

Circuit Connection:
Connect the long pin of the buzzer to pin no 0 and connect the short pin of the buzzer to GND(You can use male and female wire that is in the kit for the connection).
Don’t use register.
Code:
You have to write similar code as you write in case of LED.
Now to change the frequency of the buzzer you can use analogWrite function [ i.e analogWrite(0,255); where 255 is the frequency, it can vary from 0 to 255 ].
Here is sample code:
