Interfacing NEO-6M GPS Module with Arduino

The NEO-6M GPS module is a powerful GPS receiver that can track position, velocity, and time data. Integrating NEO-6M GPS module with Arduino UNO opens up possibilities for numerous location-based projects, such as navigation systems, vehicle tracking, or time synchronization applications. In this guide, we’ll go through the process of interfacing the NEO-6M GPS module with Arduino UNO and include a sample code to get you started.

Understanding the NEO-6M GPS Module

The NEO-6M GPS module consists of:

1. GPS Antenna: Receives signals from GPS satellites.
2. Power Supply Pins: Operates at 3.3V to 5V.
3. UART Pins (TX and RX): Used for serial communication with microcontrollers.

The module communicates via UART protocol, making it easy to interface with the Arduino UNO’s serial ports and it works on 9600 baud rate. The module is highly efficient and easy to use, making it a perfect choice for both beginners and advanced users working on GPS-based projects

Components Required

• Arduino UNO
• NEO-6M GPS Module
• Jumper wires

WIRING INSTRUCTIONS

Follow these steps to connect the NEO-6M GPS module with Arduino UNO:

The TX pin of the GPS module transmits data, while the RX pin receives data from the Arduino. To avoid direct 5V logic to the RX pin of the GPS module, ensure compatibility by using a voltage divider or logic level shifter if needed.

Library Installation

We’ll use the TinyGPSPlus library for parsing GPS data. To install this library:

1. Open the Arduino IDE.
2. Go to Sketch > Include Library > Manage Libraries.
3. Search for “TinyGPSPlus” and click Install.

Arduino Code

Here is a sample code to read and display GPS data:

#include <TinyGPSPlus.h>
#include <SoftwareSerial.h>

// Create instances of TinyGPS++ and SoftwareSerial
TinyGPSPlus gps;
SoftwareSerial gpsSerial(2, 3); // RX, TX

void setup() {
  Serial.begin(9600);         // Initialize Serial Monitor
  gpsSerial.begin(9600);      // Initialize GPS module
  Serial.println("GPS Module Initializing...");
}

void loop() {
  // Read data from GPS module
  while (gpsSerial.available() > 0) {
    char c = gpsSerial.read();
    if (gps.encode(c)) {
      displayGPSData();
    }
  }

  // If no valid data is available
  if (millis() > 5000 && gps.charsProcessed() < 10) {
    Serial.println("No GPS data received: Check connections.");
  }
}

void displayGPSData() {
  if (gps.location.isValid()) {
    Serial.print("Latitude: ");
    Serial.println(gps.location.lat(), 6);
    Serial.print("Longitude: ");
    Serial.println(gps.location.lng(), 6);
  } else {
    Serial.println("Location: INVALID");
  }

  if (gps.date.isValid()) {
    Serial.print("Date: ");
    Serial.print(gps.date.month());
    Serial.print("/");
    Serial.print(gps.date.day());
    Serial.print("/");
    Serial.println(gps.date.year());
  } else {
    Serial.println("Date: INVALID");
  }

  if (gps.time.isValid()) {
    Serial.print("Time: ");
    Serial.print(gps.time.hour());
    Serial.print(":");
    Serial.print(gps.time.minute());
    Serial.print(":");
    Serial.println(gps.time.second());
  } else {
    Serial.println("Time: INVALID");
  }

  Serial.println();
}

Testing

1. Upload the code to your Arduino UNO.
2. Open the Serial Monitor (set baud rate to 9600).
3. Place the GPS module in an open area to receive satellite signals.
4. Observe the latitude, longitude, date, and time data on the Serial Monitor.

This is how the on-board LED of the GPS module blinks when it gets signal from satellites:
