Arduino + capteur UV + ethernet + leds + envoyer des données

Question

en faisant un projet qui consiste en un arduino + bouclier ethernet + leds + capteur UV et j'ai besoin d'envoyer les données (que je reçois du capteur) à une base de données mysql

#include <Wire.h> 
#include "Adafruit_SI1145.h" 
#include <SPI.h> 
#include <Ethernet.h> 

//leds 
#include <Adafruit_NeoPixel.h> 
#ifdef __AVR__ 
    #include <avr/power.h> 
#endif 

//arduino pin usado + leds nr pins usados 
#define PIN   6 
#define NUMPIXELS  20 


Adafruit_SI1145 uv = Adafruit_SI1145(); 
Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800); 

//delay leds 
int delayval = 25; // delay for half a second 


byte mac[] = { 
    0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; 

// Enter the IP address for Arduino, as mentioned we will use 192.168.0.16 
// Be careful to use , insetead of . when you enter the address here 
IPAddress ip(192,168,137,11); 



IPAddress server(192,168,137,1); // IMPORTANT: If you are using XAMPP you will have to find out the IP address of your computer and put it here (it is explained in previous article). If you have a web page, enter its address (ie. "www.yourwebpage.com") 
//char server[] = "localhost"; 

// Initialize the Ethernet server library 
EthernetClient client; 

void setup() { 

    // Serial.begin starts the serial connection between computer and Arduino 
    Serial.begin(9600); 
pixels.begin(); 


    //start UV sensor 
    if (! uv.begin()) { 
    Serial.println("UV desligado"); 
    } 

    Serial.println ("UV ligado"); 

    // start the Ethernet connection 
    Ethernet.begin(mac, ip); 

} 

void loop() { 
if (client.connect(server,80) > 0) { 

    while(client.connected()) { 

    // get data from sensor 
    float UVindex = uv.readUV(); 
    UVindex /= 100.0; 
    Serial.print("UV BEFORE LEDS/DB");Serial.println(UVindex); 


    if(UVindex==0.02){ 
    Serial.print("UV: "); Serial.println(UVindex); 

    for(int i=0;i<NUMPIXELS;i++){ 
     pixels.setPixelColor(i, pixels.Color(150,0,0)); // Moderately bright green color. 
     pixels.show(); // This sends the updated pixel color to the hardware. 
     delay(delayval); // Delay for a period of time (in milliseconds) 
     } 

    } 
    else if(UVindex == 0.01){ 
    Serial.print("UV: "); Serial.println(UVindex); 

    for(int i=0;i<NUMPIXELS;i++){ 
     pixels.setPixelColor(i, pixels.Color(0,150,0)); // Moderately bright green color. 
     pixels.show(); // This sends the updated pixel color to the hardware. 
     delay(delayval); // Delay for a period of time (in milliseconds) 

     } 
    } 

    else if(UVindex == 0.03){ 
    Serial.print("UV: "); Serial.println(UVindex); 

    for(int i=0;i<NUMPIXELS;i++){ 
     pixels.setPixelColor(i, pixels.Color(0,0,150)); // Moderately bright green color. 
     pixels.show(); // This sends the updated pixel color to the hardware. 
     delay(delayval); // Delay for a period of time (in milliseconds) 

     } 
    } 

     // Header start 
    Serial.println("connected"); 
    client.print("GET /arduino_client_UV_VALUES/pap/getUV.php?"); 
    client.print("uv="); 
    client.print(UVindex); 
    client.println(" HTTP/1.1"); 
    client.println("Host: 192.168.137.1"); 
    //client.println("Connection: close"); 
    client.println(); 
    // Header finish 

    delay(1000); 

    } 



Serial.println(); 

    } else { 
    Serial.println(server); 
    Serial.println("connection failed"); 
    } 


    // Give the server some time to recieve the data and store it. I used 10 seconds here. Be advised when delaying. If u use a short delay, the server might not capture data because of Arduino transmitting new data too soon. 
    delay(1000); 
} 

Ceci est mon code ... mon problème est que la connexion échoue toujours, je ne sais pas quoi faire. Est-ce que quelqu'un peut m'aider?

Tout fonctionne, sauf la connexion

Essayez de changer la

suivante

IPAddress server(192,168,137,1);

à

char server[] = "192.168.137.1";
