How to test buzzer

Yeh id say its not a normal buzzer looking at that code, it would be a milliseconds I think if its the same as timeGetTime() in c++ windows code.

An alternating sequence of high and low (1 and 0) generates a square wave at the output to drive the buzzer.

delay() is in ms.

if button then buzzer=off and start a timer that counts so long, then if timer=2seconds then buzzer=back on

but ull have to get the button request to break out of that for loop that is running through the two frequencies. youll get it! welcome to hardware code. =)

I have button routine that check the status of button. When the button pressed buzzer should be give sound for 3 seconds. Then it should be turn off.

As shown in code I am calling button function in main so I only don't understand how to write code for buzzer that would be turn on for 3 seconds and then it would be turn off

Just spotted a commenting error:

Code: 
    TRISB = 0b0000001;                                    // Buzzer connected to B0
Should be:
Code: 
    TRISB = 0b0000001;                                    // Button connected to B0
Code work just the same, but the comment is confusing
