here is a link to the project: Overview | Tiny Arduino Music Visualizer | Adafruit Learning System
when i try to verify the code an error occurred
Here is the error code and i add the code as a attachment:

SIM900.h: No such file or directory
Do you have this file and if so where is it located ?
Multiple libraries were found for "GSM.h"
How many copies of this file do you have and where are they located ? How is it #included in your program ?
Did you include the libraries mentioned in the error into your sketch.
Add
#include <SIM900.h>
At the top of your sketch
Using double quotes around the 'file to include' will 'force' the compiler to first look in the directory where the sketch is.
//Edit:
It also seems to look in any subdirectory in the sketch directory.
//EndEdit
If it can't be found there, it will look elsewhere (the 'normal' directories).
If you use '<' and '>', the compiler will only look in the directories that it knows.
As you don't have the include file in the current directory, it will look elsewhere. And for the GSM it can find multiples and does not know which one to pick.

please give me step by step to solve the problem
So, where exactly is the SIM900.h file on your system ?
Also I notice this
C:\Users\user\Desktop\MakeCall.ino\MakeCall.ino.ino
That is a very odd folder structure and filename
the file sim900 i don't know where it in my system
C:\Program Files (x86)\Arduino\libraries\GSM
Change #include "SIM900.h"to#include <SIM900.h>in the code
#include <SIM900.h>
#include <SoftwareSerial.h>
#include "call.h"
#define ACTIVE LOW
const int ledPin = 13; // the number of the LED pin
//CallGSM call;
boolean started=false;
int buttonState = 1;
const int buttonPin = 7; // the number of the pushbutton pin
boolean calling = false;
void setup()
{
Serial.begin(9600);
pinMode(ledPin,OUTPUT);
pinMode(buttonPin, INPUT);
digitalWrite(buttonPin,HIGH);
if (gsm.begin(9600))
{
Serial.println("\nstatus=READY");
started=true;
}
else
Serial.println("\nstatus=IDLE");
}
void loop()
{
buttonState = digitalRead(buttonPin);
if (buttonState == ACTIVE) {
if(calling)
{
digitalWrite(ledPin,LOW);
calling = false;
call.HangUp();
delay(1000);
}else
{
calling = true;
digitalWrite(ledPin, HIGH);
delay(1000);
call.Call("+300000000000"); //Insert telephone number here
}

}
when i change #include "SIM900.h" to #include <SIM900.h> it nothing happen .. it the same problem
Can you please list the files in C:\Program Files (x86)\Arduino\libraries\GSM
Ah, a picture on google drive 
Thank god it does not work, might be a few meg big 
Try the following. Open a command prompt and type what is marked in bold
C:\Users\sterretje>[b]cd "\Program Files (x86)\Arduino\libraries\GSM"[/b]
C:\Program Files (x86)\Arduino\libraries\GSM>[b]tree /f /a[/b]
The result will look like
Folder PATH listing
Volume serial number is 58CB-3E16

Note that SIM900 is missing on my system.

Ah, a picture on google drive
That I don't appear to be able to see.
Kids today ! What's wrong with a command prompt, dir then copy/pasting the list of files ?
I also don't see it; I just checked the source in the web page and found an img tag pointing to https://drive.google.com/drive/folders/0B6cDPvXCsXmOV2k0cW5pOEcwMUE
Go there and you still don't get much (login /signup request).
