Circuit Documentation
Summary
This circuit consists of an Arduino UNO microcontroller, a SIM800L GSM Module, and a PIR Motion Sensor. The Arduino UNO serves as the central controller, interfacing with the GSM module for communication and the PIR sensor for motion detection. The circuit is designed to detect motion and potentially send notifications or alerts via the GSM module.

This code initializes the Arduino UNO and sets up the main loop. The setup function is intended for initialization code that runs once, while the loop function contains the main code that runs repeatedly. The code is currently a template and does not include specific functionality for the PIR sensor or GSM module.
