    There are different kinds of GSM modules available in market. We are using the most popular module based on Simcom SIM900A and Arduino Uno for this tutorial. Interfacing a GSM module to Arduino is pretty simple. You only need to make 3 connections between the gsm module and arduino. So lets get to business!
    A GSM Module is basically a GSM Modem (like SIM 900) connected to a PCB with different types of output taken from the board - say TTL Output (for Arduino, 8051 and other microcontrollers) and RS232 Output to interface directly with a PC (personal computer). The board will also have pins or provisions to attach mic and speaker, to take out +5V or other values of power and ground connections. These type of provisions vary with different modules.
    Lots of varieties of GSM modem and GSM Modules are available in the market to choose from. For our project of connecting a gsm modem or module to arduino and hence send and receive sms using arduino - its always good to choose an arduino compatible GSM Module - that is a GSM module with TTL Output provisions.
