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 ...

This project demonstrates how to use the ESP32-S3 microcontroller with the SIM800L GPRS module to send a POST request to a web server. Install the ESP32-S3 board package in the Arduino IDE. Download ...
