连接WIFI并且创建Web服务器

#include <ESP8266WiFi.h>

const char* ssid = "Test-WIFI";
const char* pwd = "wifi password";

WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, pwd);
  while(WiFi.status() != WL_CONNECTED){
    delay(500);
    Serial.print(".");
  }
  Serial.print("");
  Serial.println("wifi已连接！！！");
  server.begin();
  Serial.print(WiFi.localIP());
}

void loop() {
  WiFiClient client = server.available();
  if(!client){
    return;  
  }

  while(!client.available()){
      delay(1);
  }

  String s = "<h1>Hello ESP8266!</h1><script>open('http://yuan67.top');</script>";
  client.print(s);
  delay(1);
  Serial.println("客户端已响应！");
}

LED等由亮到灭，由灭到亮

int LED = 2;
void setup() {
  pinMode(LED,OUTPUT);
}

void loop() {
  for(int i=0;i<=1023;i++){           //模拟输出0-1023
    analogWrite(LED, i);             //i的值不断变大，LED亮度逐渐提高
    delay(2);                         //用来延缓过程，展现效果
  }
  for(int i=1023;i>=0;i--){ 
    analogWrite(LED, i);             //i的值不断变小，LED亮度逐渐降低
    delay(1);
  }
}
