Circuit Documentation

Summary

This document provides a detailed overview of a circuit involving three Arduino Mega 2560 microcontrollers and a GPS NEO 6M module. The circuit is designed to interface the GPS module with one of the Arduino Mega 2560 boards, allowing it to read and print GPS data to the Serial Monitor. The other two Arduino Mega 2560 boards are included but not connected to the GPS module.
