GPS Tracking System

Welcome to the GPS Tracking System project! This project is a real-time GPS location tracking system built using the ESP8266 microcontroller and the NEO-6M GPS module. It showcases how to obtain and display GPS coordinates in real time, and includes an interactive user experience with emojis for better readability and engagement.

Installation

Prerequisites

• Arduino IDE (or any compatible IDE)
• USB-to-serial adapter or micro-USB cable
• ESP8266 libraries installed in the Arduino IDE

Setup

1. Clone the repository:

   git clone https://github.com/OtakuNoDev/GPS_project.git
   cd GPS_project

2. Install the required libraries in the Arduino IDE:

   • Adafruit_GFX Library
   • Adafruit GPS Library
   • ESP8266WiFi Library

3. Connect the hardware:

   • NEO-6M GPS module to ESP8266 (using UART pins).
   • Ensure correct power and ground connections.

4. Open the project in Arduino IDE and upload the code to the ESP8266.

Usage

#include <SoftwareSerial.h>
#include <TinyGPS++.h>
#include <ESP8266WiFi.h>

#define RX_PIN 4  // GPS TX to ESP8266 RX (GPIO 4)
#define TX_PIN 5  // ESP8266 TX to GPS RX (GPIO 3, usually not used)

// Wi-Fi credentials
const char* ssid = "SSID";        // Replace with your Wi-Fi SSID
const char* password = "PASSWORD"; // Replace with your Wi-Fi password

// Create a SoftwareSerial object
SoftwareSerial GPS_SoftSerial(RX_PIN, TX_PIN);
TinyGPSPlus gps;
WiFiServer server(80); // Create a web server on port 80

void setup() {
    Serial.begin(115200);           // Start Serial Monitor
    WiFi.begin(ssid, password);     // Connect to Wi-Fi

    while (WiFi.status() != WL_CONNECTED) {
        delay(1000);
        Serial.println("🌐 Connecting to WiFi...");
    }

    Serial.println("✅ Connected to WiFi");
    server.begin();                 // Start the server
    Serial.println("🚀 Server started");
    GPS_SoftSerial.begin(9600);     // Start SoftwareSerial for GPS
}

void loop() {
    while (GPS_SoftSerial.available()) {
        gps.encode(GPS_SoftSerial.read());
        if (gps.location.isUpdated()) {
            double latitude = gps.location.lat();
            double longitude = gps.location.lng();
            String url = "http://maps.google.com/?q=" + String(latitude, 6) + "," + String(longitude, 6);

            // Print location details to Serial Monitor with emojis
            Serial.println("📍 Location Updated:");
            Serial.print("   🗺️ Latitude: ");
            Serial.println(latitude, 6);
            Serial.print("   🗺️ Longitude: ");
            Serial.println(longitude, 6);
            Serial.println("🔗 Google Maps Link: " + url);

            // Handle client connections
            WiFiClient client = server.available();
            if (client) {
                Serial.println("🌟 New client connected");
                String response = "HTTP/1.1 302 Found\r\n";
                response += "Location: " + url + "\r\n";
                response += "Connection: close\r\n";
                response += "\r\n";
                client.print(response);
                delay(100); // Give the client time to receive the data
                client.stop(); // Close the connection
                Serial.println("👋 Client disconnected");
            }
        }
    }
}

This code retrieves GPS coordinates and sends them to the serial monitor or a connected web interface.

Local Development

This local development setup is for testing and running the GPS tracking system on your ESP8266 module.

Steps

1. Install dependencies:

   arduino-cli core install esp8266:esp8266

2. Upload to ESP8266: Open the .ino file in Arduino IDE, connect the ESP8266, and upload the code.

3. Test the output: Use a serial monitor to view the GPS coordinates in real time.
