/****** DEFINITION OF LIBRARIES *****/
#include <Adafruit_GFX.h>   //https://github.com/adafruit/Adafruit-GFX-Library
#include <Adafruit_TFTLCD.h> // Include the TFT LCD library (assumed needed for tft instance)

// Define the pins for the TFT LCD
#define TFT_CS     10
#define TFT_RST    9
#define TFT_DC     8

// Create an instance of the TFT LCD
Adafruit_TFTLCD tft(TFT_CS, TFT_DC, TFT_RST); // Create an instance of the TFT LCD

// Speed variable
int speed = 0; // Speed in km/h (initialized to 0)

// Function to display speed on the TFT
void displaySpeed(int speed) {
    // Clear the previous speed display
    tft.fillRect(0, 0, 240, 40); // Clear the area for speed display

    // Display the speed
    tft.setCursor(10, 10);
    tft.print("Speed: ");
    tft.print(speed);
    tft.print(" km/h");
}

void setup(void)
{
    // put your setup code here, to run once:
    tft.begin(); // Initialize the TFT
    tft.setRotation(1); // Set the rotation of the screen
    tft.fillScreen(WHITE); // Fill the screen with white

    // Set text properties
    tft.setTextColor(BLACK);
    tft.setTextSize(3);
}

void loop(void)
{
    // put your main code here, to run repeatedly:
    // Simulate speed changes (for testing purposes)
    speed = random(0, 200); // Random speed between 0 and 200 km/h

    // Call function to display the updated speed
    displaySpeed(speed);

    delay(1000); // Update every second
