Full Code

#include <TinyGPS++.h>
#include <SoftwareSerial.h>

static const   int RXPin = 4, TXPin = 3;
static const uint32_t GPSBaud = 9600;

// The   TinyGPS++ object
TinyGPSPlus gps;

// The serial connection to the GPS   device
SoftwareSerial ss(RXPin, TXPin);

void setup(){
  Serial.begin(9600);
   ss.begin(GPSBaud);
}

void loop(){
  // This sketch displays information   every time a new sentence is correctly encoded.
  while (ss.available() > 0){
     gps.encode(ss.read());
    if (gps.location.isUpdated()){
      Serial.print("Latitude=   "); 
      Serial.print(gps.location.lat(), 6);
      Serial.print(" Longitude=   "); 
      Serial.println(gps.location.lng(), 6);
    }
  }
}

Code Explanation

The following code is designed to read GPS data.

Libraries Used:

The TinyGPS++ and SoftwareSerial libraries are used. The TinyGPS++ library is specifically designed for GPS data parsing.

#include <TinyGPS++.h>  
#include <SoftwareSerial.h>  

Pin Definitions and Setup:

static const int RXPin = 4, TXPin = 3;  
static const uint32_t GPSBaud = 9600;  
TinyGPSPlus gps;  
SoftwareSerial ss(RXPin, TXPin);  

Main Loop:

After encoding GPS data, it prints the latitude and longitude on the serial monitor.

if (gps.location.isUpdated()) {  
    Serial.print("Latitude= ");   
    Serial.print(gps.location.lat(), 6);  
    Serial.print(" Longitude= ");   
    Serial.println(gps.location.lng(), 6);  
}  

Library Installation

1. Open the Arduino IDE.
2. Go to Sketch > Include Library > Manage Libraries.
3. Search for TinyGPS++ and install it.

Uploading the Code and Viewing Results

1. Connect the Arduino to Your PC:
   Use a USB cable to connect the Arduino board to your computer. Ensure the connection is secure.
2. Open the Arduino IDE:
   Launch the Arduino IDE on your computer and create a new sketch or open an existing one.
3. Write or Paste the Code:
   Copy the provided code for the Neo 6M GPS module and paste it into the Arduino IDE. Make sure the code is error-free and the required libraries (e.g., TinyGPS++ and SoftwareSerial) are already installed.
4. Select the Correct COM Port:
   Navigate to Tools > Port in the Arduino IDE and select the COM port associated with your Arduino board. This ensures the IDE communicates with the correct device.
5. Upload the Code:
   Click on the upload button in the Arduino IDE (the arrow pointing to the right). Wait for the code to compile and upload to the Arduino board. The “Done Uploading” message will confirm successful uploading.
6. Open the Serial Monitor:
   After uploading, open the Serial Monitor in the Arduino IDE by clicking on Tools > Serial Monitor. Set the baud rate to 9600 to match the communication speed of the Neo 6M GPS module.
7. View GPS Data:
   In the Serial Monitor, you will see the GPS data, including latitude and longitude values. These values represent your current location, provided the GPS module has acquired a signal from satellites.
