Circuit Documentation
Summary
This circuit integrates multiple components, including an Arduino Mega 2560 microcontroller, an LCD 20x4 with I2C interface, a Hall sensor, a DHT11 temperature and humidity sensor, and a GPS NEO-6M V2 module. The Arduino Mega 2560 serves as the central processing unit, interfacing with the sensors and the LCD to display data or perform other functions as programmed. The GPS module provides location data, the Hall sensor detects magnetic fields, and the DHT11 sensor measures environmental conditions. The LCD displays information to the user. Power distribution is managed through common 5V and GND nets, and communication between devices is established via digital and I2C connections.
