Interfacing GSM Module with Arduino

In this article, I am going to explain about interfacing of GSM Module with Arduino. Interfacing a GSM module to Arduino is pretty simple. We have to make only 3 connections between the GSM module and Arduino. For the working demonstration we will be sending an SMS to a particular number whenever a switch is pressed.
