2. 韌體更新網址 http://arduino.esp8266.com/stable/package_esp8266com_index.json

## 基礎練習

### 練習一:Hello World
在模擬軟體上練習如何顯示出Hello World

void setup()
{
	Serial.begin(9600);
}

void loop()
{
    Serial.println("Hello World");
    delay(100);
}

### 練習二: led 顯示

void setup()
{
    Serial.begin(9600);
    pinMode(2, OUTPUT);
}

void loop()
{
    digitalWrite(2, HIGH); 
    delay(1000);
    digitalWrite(2, LOW); 
    delay(1000);
}

### 練習三: 簡易紅綠燈

void setup()
{
	Serial.begin(9600);
  	pinMode(3, OUTPUT);
	pinMode(4, OUTPUT);
 	pinMode(5, OUTPUT);
}

void loop()
{
        digitalWrite(3, LOW);
        digitalWrite(5, HIGH); 
        delay(5000);
        digitalWrite(5, LOW); 
        digitalWrite(4, HIGH);
        delay(2000);
        digitalWrite(4, LOW); 
        digitalWrite(3, HIGH);
        delay(5000);
}

### Serial 輸入練習

void setup()
{
  	Serial.begin(38400);
}

void loop()
{
  if(Serial.available())
  {
      while(Serial.available()){
          Serial.print((char)Serial.read());
          delayMicroseconds(250);
      }
      Serial.println();
  }
}

## 進階紅綠燈練習

    pinMode(3, OUTPUT);
    pinMode(4, OUTPUT);
    pinMode(5, OUTPUT);
}

bool isStart = false;
unsigned long time;


void loop()
{
  //Reading now times
  time = millis() / 1000;
    	
  //Reading UserIn Command
  if(Serial.available()){
      char userIn = (char)Serial.read();
      if(userIn == 'S')
      {
        Serial.println("Start");

        digitalWrite(3, LOW);
        digitalWrite(4, LOW);
        digitalWrite(5, LOW); 
      }            
    }

    //Running Thread if isStart is true
    if(isStart)
    {
      switch(time % 8)
      {
          case 0:
          case 1:

## 常見 Restful API 操作

1.重新設定網路
http://localhost/rest/

2.GPIO 控制(輸出)
http://localhost/gpio?腳位=值
http://localhost/gpio?7=1

3.GPIO 控制(讀取)
http://localhost/gpio/read?腳位=
http://localhost/gpio/read?7=

4.PWM 控制(輸出)
http://localhost/gpio/pwm?腳位=值
http://localhost/gpio/pwm?7=1023

5.讀取類比訊號(輸入)
http://localhost/gpio/adc

6.DHT11 Reader
http://localhost/dht?pin=5&type=11

## Restful API

//建立HTTP 連線並取得資料
while (true)
{
    //建立HTTP 連線並取得資料
    using (HttpClient client = new HttpClient())
    {
        client.BaseAddress = new Uri("http://192.168.0.114");
        HttpResponseMessage response = client.GetAsync("dht11?5=").Result;
        response.EnsureSuccessStatusCode();
        string result = response.Content.ReadAsStringAsync().Result;

        JObject jo = JObject.Parse(result);
        if (jo.HasValues)
        {
            Console.WriteLine("目前的室內溼度為:{0}%,溫度為:{1}度", jo.GetValue("Humidity"),jo.GetValue("C"));    
        }
    }
    Thread.Sleep(1000);
}
