arduino+wifi shield链接yeelink控制led 的问题
在yeelink官网上和其 它网络上多是w5100联网的案例，我用的是wifi shield网页设置好wifi，控制led，代码（来自论坛）如下：boolean ResponseBegin = false;
String returnValue = "";
unsigned long previousMillis = 0;
unsigned long interval = 900;
char c ;
void setup()
{
Serial.begin(115200);
pinMode(13,OUTPUT);
}
void loop()
{
if(Serial.available())
c = Serial.read();
if(c == '{')
ResponseBegin = true;
if(c == '}')
ResponseBegin = false;
if (ResponseBegin)
returnValue += c;
if (returnValue.length() !=0 && (ResponseBegin == false))
{
if(returnValue.charAt(returnValue.length() - 1) == '1')
{digitalWrite(13,HIGH);Serial.println("ON");}
if(returnValue.charAt(returnValue.length() - 1) == '0')
{digitalWrite(13,LOW);Serial.println("OFF");}
returnValue = "";
}
unsigned long currentMillis = millis();
if(currentMillis - previousMillis > interval)
{
previousMillis = currentMillis;
Serial.println("GET /v1.0/device/7794/sensor/12316/datapoints HTTP/1.1"); //“/device/4290/sensor/9970/”device,sensor 后面的数值用你自己的替代
Serial.println("Host: api.yeelink.net");
Serial.print("Accept: *");
Serial.print("/");
Serial.println("*");
Serial.print("U-ApiKey: ");
Serial.println("****************"); // 此处用你的APIKEY替代
Serial.println("Content-Length: 0");
Serial.println("Connection: close");
Serial.println();
}
}
总是实现不了控制led的功能，请问怎么回事》谢谢
参考下这个吧！#include <EtherCard.h>
