连接方法：

修改WIFI：

关键代码

void setup()
{
  Serial.begin(115200);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid,password);
  Serial.print("\r\nConnecting to ");//serial：串口函数，serial.print：经由串口的打印函数
  Serial.print(ssid);
  Serial.println("...");
 
  while(WiFi.status()!= WL_CONNECTED)
  {//返回值由WiFi连接状态决定
    delay(1000);//while循环每一秒检查一次
    Serial.print("Waiting for ");
   // Serial.print(j++);
    Serial.println("sss...");
  }
