Arduino SIM800L HTTP connector Arduino driver for GSM/GPRS module SIMCom SIM800L to make HTTP/S connections with GET and POST methods This is a comprehensive Arduino library to make HTTP or HTTPS ...

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 ...

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 ...

Thank you for your interest in this project. Unfortunately, this project is no longer maintained as I no longer have a functionning SIM800L module. Additionally, the SIM800L doesn't support current ...

Here we are using a 2596 buck converter for providing a constant voltage of 4.2 Volts as the GSM SIM800L module is a power hungry device that will require more current while using the GPRS. To know ...

LilyGo has launched several TTGO boards usually based on Espressif ESP8266 or ESP32 over the years. Here’s another that could be useful if 2G cellular networks have not sunset in your country: TTGO ...
