我正在制作一个由 arduino + 以太网屏蔽 + LED + UV 传感器组成的项目,我需要将数据(我从传感器接收到的)发送到 mysql 数据库

#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);
}

这是我的代码...我的问题是连接总是失败,我不知道该怎么办。有人能帮我吗?

除了连接之外一切正常

最佳答案

尝试更改以下内容

IP地址服务器(192,168,137,1);

字符服务器[] = "192.168.137.1";
