Circuit Documentation

Summary

This document describes a simple GPS interfacing circuit using an Arduino UNO and a GPS NEO 6M module. The Arduino UNO microcontroller board is used to communicate with the GPS module and relay the GPS data to a connected computer via serial communication. The GPS module receives power from the Arduino and communicates with it using serial data lines.

This code sets up a software serial connection on pins D3 and D4 of the Arduino UNO to communicate with the GPS NEO 6M module. It initializes the serial communication at a baud rate of 9600 bps. The loop() function continuously checks for data from the GPS module and forwards it to the Serial Monitor when available.
