The SIM800L module needs special attention because it operates at 3.3V logic levels while Arduino uses 5V. We need a voltage divider circuit to protect the SIM800L from damage. If you are new to the ...

This project monitors voltage using a potentiometer connected to an Arduino. When the voltage reaches 4.8V or higher, the system automatically sends an SMS and makes a phone call using the SIM800L GSM ...

A microcontroller-based GPS tracking project using the SIM800L GSM module and the NEO-6M GPS module. The device collects real-time GPS coordinates and sends them over GSM to a remote web server, where ...
