About HIGH SCHOOL PROJECT - The purpose of this Arduino library is to allow the use of the SIM800L module in a simple and transparent way.

GSM-Based-Voltage-Alert-System-using-Arduino-SIM800L This project monitors voltage using a potentiometer connected to an Arduino. When the voltage reaches 4.8V or higher, the system automatically ...

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 ...

The Fingerprint Door Lock (FPDL) using Arduino with SIM800L research is designed to improve the security and convenience of door access control by integrating fingerprint recognition with Arduino and ...
