GSM for Arduino microcontrollers - the easy way into the communication network

The terms "GSM" (Global System for Mobile Communication) and "GPRS" (General Packet Radio Service) are familiar to many hobbyists, especially the amateur radio operators among you. They serve as a synonym definition for mobile radio standards. But what is behind it?
In short: If you equip a microcontroller with a GSM or GPRS capable module, it can communicate with other devices in the network via SMS, voice call or the Internet.
Example of use? If you equip an Arduino microcontroller with a SIM808L module, you can be conveniently notified if, for example, you forgot to close the kitchen window or turn off the washing machine. In general, any signal that can be detected and processed by a single-board computer is suitable as a pulse generator and thus as a "starting signal" for GSM communication.

SIM8000L GSM / GPRS module for Arduino - a simple example

The wiring of a GSM module and an Arduino microcontroller is very simple, you can find many tutorials on the net. A bit more exciting is the functionality of the module itself, because the SIM808L module is not directly suitable for GSM. You need an activated 2G micro SIM, which has to be plugged in at the bottom of the board. Once this is installed, programming is done via AT command within the Arduino IDE.
