SIM800L & Arduino Uno . Advertisement. Hardware. To start, set up the hardware as shown below. Naturally, you’re going to need a valid SIM card to fully use the SIM800L module. For compactness, my ...

Sim800L Arduino Library revised. The SIM800L Arduino Library is a simple and easy-to-use library for the SIM800L module, allowing for quick and efficient communication with the module using the ...

A PCB layout of the GSM security switch is shown in Fig. 4 and its components layout in Fig. 5. Upload the source code to Arduino Nano and then insert it into the PCB. Solder the spiral antenna on ...

The code (Arduino sketch) is a basic one without any dedicated SIM800L libraries. In the code, the RX and TX pins are assigned as software serial pins. This is done deliberately so that the Arduino’s ...
