Arduino Based Vehicle Accident Alert system program

Welcome to my website 

Hello friends, in this project we are going to make an Arduino based vehicle accident alert system using Arduino Uno, GPS Module, GSM and ADXL are the main components of the project. ADXL detects real time changes in vehicle axis and GSM module sends alert message to your mobile with location of vehicle accident. When you save the ambulance number in the program, the ambulance will arrive at the accident location, the vehicle accident location is sent as a google map link created from the latitude and longitude from the GPS module and the 16*2 LCD display shows the current information of the project and the arduino uno controls the complete system. the main purpose of the project is that after the accident, the life of the passengers should be saved as soon as possible.
