Circuit Documentation

Summary

The circuit in question is designed around two Arduino UNO microcontrollers, which serve as the central processing units. The circuit includes a variety of sensors and modules to perform different functions. These include an MPU-6050 for motion tracking, a GPS NEO 6M module for location tracking, a rain sensor for detecting rainfall, and a LoRa module for long-range communication. Additionally, the circuit features a buzzer module for audio feedback and an LCD screen with I2C interface for displaying information. The components are powered through the 5V and GND pins of the Arduino UNOs, and communication between the sensors, modules, and the Arduino is established via digital and analog I/O pins, as well as I2C communication lines.
