In this project i have used sim900a(GSM),GPS,and vibration sensor.My code was successfully compiled and got output on serial monitor(latitude longitude) But unable to get message on my mobile from gsm module Pls help me to get output

My code is

#include<LiquidCrystal.h>
LiquidCrystal lcd(2,3,4,5,6,7);

#define vibrate_sense 9

char str[70];
char *test="$GPGGA";
char logitude[10];
char latitude[10];

int i,j,k;
int temp;
//int Ctrl+z=26; //for sending msg
int led=13;

void setup()
{
lcd.begin(16,2);
Serial.begin(4800);
pinMode(vibrate_sense, INPUT);
pinMode(led, OUTPUT);
lcd.setCursor(0,0);
lcd.print("GPS Besed Vehicle ");
lcd.setCursor(0,1);
lcd.print("Tracking System");
delay(3000);
}

void loop()
{
if (digitalRead(vibrate_sense)==0)
{
for(i=18;i<27;i++) //extract latitude from string
{
latitude[j]=str*;*

  • j++;*

  • }*

  • for(i=30;i<40;i++) //extract longitude from string*

  • {*
    _ logitude[k]=str*;_
    _     k++;_
    _     }*_

* lcd.setCursor(0,0); //display latitude and longitude on 16X2 lcd display*
* lcd.print("Lat(N)");*
* lcd.print(latitude);*
* lcd.setCursor(0,1);*
* lcd.print("Lon(E)");*
* lcd.print(logitude);*
* delay(100);*
* Serial.begin(9600);*
* Serial.println("AT+CMGF=1"); //select text mode*
* delay(10);*
* Serial.println("AT+CMGS="78xxxxxx""); // enter receipent number*
* Serial.println("Vehicle Accident Happend at Place:");*
* Serial.print("Latitude(N): "); //enter latitude in msg*
* Serial.println(latitude); //enter latitude value in msg*
* Serial.print("Longitude(E): "); //enter Longitude in Msg*
* Serial.println(logitude); //enter longitude value in msg*
* Serial.print("Help Please");*
* Serial.write(26); //send msg Ctrl+z=26*
* temp=0;*
* i=0;*
* j=0;*
* k=0;*
* delay(20000); // next reading within 20 seconds*
* Serial.begin(4800);*
* }*
}
void serialEvent()
{
* while (Serial.available()) //Serial incomming data from GPS*
* {*
* char inChar = (char)Serial.read();*
_ str*= inChar; //store incomming data from GPS to temparary string str[]
 i++;
 if (i < 7)
{
 if(str[i-1] != test[i-1]) //check for right string*
* {
 i=0;
 }
 }
 if(i >=60)
 {
 break;
 }
 }
}*_

Well, your code is already meaningless - as you may note by the italics - because you did not post it correctly.

Go and read the instructions, then go back and modify your post (use the "More --> Modify" option to the bottom right of the post) to mark up the code as such so we can examine it conveniently and accurately.

Note: Also mark up any data in the same way. This includes error output that you get from the IDE.
