Circuit Documentation

Summary

This document provides a detailed overview of a GPS tracking circuit that utilizes an Arduino Nano microcontroller and a GPS NEO 6M module. The Arduino Nano is programmed to communicate with the GPS module to receive and process GPS data, which includes latitude, longitude, altitude, and the number of satellites in view. The processed data is then output to the Serial Monitor for real-time tracking.

Description: This Arduino sketch initializes a SoftwareSerial connection to the GPS NEO 6M module on pins D4 and D3. It reads incoming GPS data and uses the TinyGPS++ library to parse the data. When a new location is available, it prints the latitude, longitude, altitude, and the number of satellites to the Serial Monitor.
