Programming help, Arduino GPS Speed

Hello,
we are working on a discovery project concerning coding on arduino cards. We must acquire the GPS speed using a module and the TinyGPS ++ GPS library and thus display it on an I2C display to subsequently carry out a simulation on Proteus.
You will find attached a copy of our program (which obviously does not work :roll_eyes: ).

Thank you in advance for your answers and your indulgence towards our incompetence.

The SSI group, Lycée Charles de Gaulle, Muret, FRANCE :sunglasses:

Arduino Code :

#include <LiquidCrystal_I2C.h>
#include <Wire.h>
#include <TinyGPS++.h>
#include <liquidcrystal_I2C.h>
#include <SoftwareSerial.h>

static const int RXPin = 4, TXPin = 3;
static const uint32_t GPSBaud = 4800;

// The TinyGPS++ object
TinyGPSPlus gps;

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

// set the LCD address to 0x27 for a 16 chars and 2 line display
LiquidCrystal_I2C lcd(0x27,20,4);

float vitesse; //crée la variable vitesse

void setup()
{
lcd.init();
lcd.setCursor(0,0);
Serial.begin(115200);
ss.begin(GPSBaud);
}

void loop()
{
while (ss.available() > 0)
{
gps.encode(ss.read());
if (gps.speed.isUpdated())
{
Serial.print(“VITESSE=”); Serial.println(gps.speed.kmph());
vitesse=gps.speed.kmph();
lcd.print("VITESSE ");lcd.print(vitesse);
delay(500);
lcd.clear();
}

}

}

"Does not work" is an insufficient description of the problem. Does the code compile? What does the code do that is not right?

Why include 2 liquid crystal libraries? And I am pretty sure that the liquidcrystal_I2C.h does not exist.
