GSM/GPRS Projects Based on PIC Microcontrollers and Arduino

Every mobile phone includes a GSM/GPRS modem which enables the phone to communicate with the external world. With the help of the GSM modems, users can establish audio conversations and send and receive SMS text messages. In addition, the GPRS modem enables users to connect to the internet and to send and receive large files such as pictures and video over the internet. This book is aimed for the people who may want to learn how to use the GSM/GPRS modems in microcontroller based projects. Two types of popular microcontroller families are considered in the book: PIC microcontrollers, and the Arduino. The highly popular mid-performance PIC18F87J50 microcontroller is used in PIC based projects together with a GSM Click board. In addition, the SIM900 GSM/GPRS shield is used with the Arduino Uno projects. Both GSM and GPRS based projects are included in the book. The book will enable you to control equipment remotely by sending SMS messages from your mobile phone to the microcontroller, send the ambient temperature readings from the microcontroller to a mobile phone as SMS messages, use the GPRS commands to access the internet from a microcontroller, send temperature readings to the cloud using UDP and TCP protocols and so on. It is assumed that the reader has some basic working knowledge of the C language and the use of microcontrollers in simple projects. Although not necessary, knowledge of at least one member of the PIC microcontroller family and the Arduino Uno will be an advantage. It will also be useful if the user has some knowledge of basic electronics. All project software is available to download for free at the Elektor website.
