i have big problem with these i gsm module is not sending the location of the vehicle
iam using
1.arduino uno board
2.16*2 lcd display for cross checking my location
3.gsm module sim900A
4.gps module royaltek ReB 4612
5.vibration sensor for detecting the vibrations
6.buzzer for sounding when even their is an accident
here is my code plz let me know faults in my code
#include <SoftwareSerial.h>
#include<LiquidCrystal.h>
#define buzzer 8
#define E 9 //vibration sensor
