GPS With Arduino R4-IoT Cloud

This project aims to use the NEO-6M GPS sensor with Arduino R4 to collect location data and transmit it to a map widget on an IoT cloud platform. The goal is to assess the precision of latitude and longitude values obtained from the sensor. By confirming the accuracy of these coordinates, the project seeks to validate the dependability of GPS data gathering with Arduino for various purposes, including real-time monitoring of GPS locations via mobile phones.

Arduino R4 Board with Cable: The Arduino microcontroller serves as the central processing unit for interfacing with the GPS module and processing the data received from it. The cable facilitates the connection between the Arduino board and the computer for programming and power supply.

GPS NEO-6M Sensor: The NEO-6M GPS module is a compact and cost-effective device capable of providing accurate positioning data through satellite communication. It receives signals from GPS satellites to determine latitude, longitude, altitude, and time information.

4 Wires Female to Male: These wires are essential for establishing connections between the Arduino board and the NEO-6M GPS sensor. They enable the transmission of data and power between the two components, facilitating communication and functionality.

Note: In the circuit diagram picture, I used the Arduino R3, but the connections remain the same for the Arduino R4.

TX and RX Connections: Connect TX pin of NEO-6M to Arduino's digital pin 2 (RX), and RX pin of NEO-6M to Arduino's digital pin 3 (TX).

Voltage Connection: Ensure VCC pin of NEO-6M is linked to Arduino's 3.3V output to supply the correct voltage, preventing potential module damage.

#include "thingProperties.h"

This line includes the thingProperties.h file, which contains definitions for properties used in the Arduino IoT Cloud.

#include <TinyGPSPlus.h>

This line includes the TinyGPSPlus library, which is used for parsing GPS data.

#include <SoftwareSerial.h>

This line includes the SoftwareSerial library, which is used for creating a secondary serial port on digital pins.

SoftwareSerial serial_connection(2,3);

This line initializes a SoftwareSerial object named serial_connection on pins 2 (RX) and 3 (TX).

TinyGPSPlus gps;

This line initializes a TinyGPSPlus object named gps for parsing GPS data.

ArduinoCloud.update();

This line updates the connection with Arduino IoT Cloud.

while(serial_connection.available()) { ... }

This loop reads data from the secondary serial port (connected to the GPS module) and parses it using TinyGPSPlus.

if (gps.location.isUpdated()) { ... }

This condition checks if a new GPS location is available. If true, it retrieves the latitude and longitude from the GPS data and prints them.

This code snippet demonstrates how to integrate a GPS module with Arduino IoT Cloud, allowing you to monitor and track location data remotely.

The result will be presented through videos and pictures to ensure clarity of the idea.
