Introduction

This experiment demonstrates how to use a GPS module with an Arduino to retrieve location data like latitude and longitude.

Components Needed

• GPS Module
• Arduino (e.g., Uno, Nano)
• Jumper wires

No Ads Available.

Circuit Setup

1. Connect the GPS module's TX and RX pins to the Arduino's RX and TX pins, respectively.
2. Connect the GND and VCC pins of the GPS module to the Arduino's GND and 5V pins.

The GPS module will send location data to the Arduino.

Code for GPS Module with Arduino

Upload the following code to your Arduino to retrieve and display GPS data:

#include 
#include 

SoftwareSerial ss(4, 3);  // RX, TX
TinyGPSPlus gps;

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

void loop() {
  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);
    }
  }
}
            

Explanation

The GPS module retrieves location data from satellites, which is then processed by the Arduino and displayed via the Serial Monitor.

Troubleshooting

• If the GPS module isn't working, check the wiring, and ensure the module has a clear view of the sky for satellite connection.
• If the location data is inaccurate or unavailable, try waiting for a better GPS signal.
