You can install the Sim800L Arduino Library in the Arduino IDE by going to Sketch > Include Library > Manage Libraries, searching for "Sim800L" and clicking on the ...

This is my idea of what serial communication with gsm-sim800l could look like. There are all sorts of different libraries for different gsm-sim800l modules. I have included simple code for sending and ...

It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...

Because the SIM800L module is very flexible, a great GSM project design can be relatively simple. But there are a number of reasons for experimenting with more complex ideas, such as enhanced ...
