GY-GPS6MV2 Module

I am currently working on my graduation project and ı have to use gy-gps6mv2 module for that

my connection:

3.3V to Vcc
Gnd to Gnd
digital-3 to rx
digital-4 to tx

I am using Tinygps, here is the code:

#include <SoftwareSerial.h>

#include <TinyGPS.h>

/* This sample code demonstrates the normal use of a TinyGPS object.
It requires the use of SoftwareSerial, and assumes that you have a
4800-baud serial GPS device hooked up on pins 4(rx) and 3(tx).
*/

TinyGPS gps;
SoftwareSerial ss(4, 3);

static void smartdelay(unsigned long ms);
static void print_float(float val, float invalid, int len, int prec);
static void print_int(unsigned long val, unsigned long invalid, int len);
static void print_date(TinyGPS &gps);
static void print_str(const char *str, int len);

void setup()
{
Serial.begin(115200);

Serial.print(“Testing TinyGPS library v. “); Serial.println(TinyGPS::library_version());
Serial.println(“by Mikal Hart”);
Serial.println();
Serial.println(“Sats HDOP Latitude Longitude Fix Date Time Date Alt Course Speed Card Distance Course Card Chars Sentences Checksum”);
Serial.println(” (deg) (deg) Age Age (m) — from GPS ---- ---- to London ---- RX RX Fail”);
Serial.println("-------------------------------------------------------------------------------------------------------------------------------------");

ss.begin(9600);
}

void loop()
{
float flat, flon;
unsigned long age, date, time, chars = 0;
unsigned short sentences = 0, failed = 0;
static const double LONDON_LAT = 51.508131, LONDON_LON = -0.128002;

print_int(gps.satellites(), TinyGPS::GPS_INVALID_SATELLITES, 5);
print_int(gps.hdop(), TinyGPS::GPS_INVALID_HDOP, 5);
gps.f_get_position(&flat, &flon, &age);
print_float(flat, TinyGPS::GPS_INVALID_F_ANGLE, 10, 6);
print_float(flon, TinyGPS::GPS_INVALID_F_ANGLE, 11, 6);

print_str(flat == TinyGPS::GPS_INVALID_F_ANGLE ? "*** " : TinyGPS::cardinal(TinyGPS::course_to(flat, flon, LONDON_LAT, LONDON_LON)), 6);

gps.stats(&chars, &sentences, &failed);
print_int(chars, 0xFFFFFFFF, 6);
print_int(sentences, 0xFFFFFFFF, 10);

Serial.println();

smartdelay(1000);
}

    I already changed 4800 value to 9600, but here is my readings:

    Any kind of help is appreciated, ı am new to arduino btw

Ugh. Read the "How to Use this Forum" at the top of the previous page.

You have orders of magnitude WAY TOO MUCH code for someone that does not know what is being read from the GPS.

Read a character from the GPS. Print it to the Serial Monitor application. NOTHING else, until you are getting good data from the GPS.
