项目描述

此项目通过使用Ethernet Shield及Twitter推送来控制一个情景灯。

步骤1：材料

这个项目用到了很少的材料，有很多是不必要的。你也可以改变灯的外形，这样可能会用到更少材料。

电子零件

Arduino Uno R3（我买了一个SainSmart版本，以削减成本）
Arduino Ethernet Shield（我在Radio Shack只花了10美金就搞定了）
4个Led
网线
电源适配器
焊锡

装饰材料

亚克力盒子（我在沃尔玛仓储区找到了一个预制的）
少量约1/2英尺厚的木头
橡胶垫脚
木染料
磨砂玻璃喷漆
泡沫塑料（用来放Arduino）
单乙烯基（做一个可在亚克力上喷漆的模具）
钉子
木胶

需要工具

烙铁
电钻
射钉枪
热胶枪
模切绘图机（用于磨具，不必须有）

步骤2：电子器件构建

受电子知识的限制，我尽量将一切简化。我把led灯直接焊接在了Ethernet Shield上。使用了12和13端口。而前后讲Ethernet Shield插入到Arduino对应引脚上。

步骤3：木头盒子

我构建了一个木头盒子，这样亚克力盒子就能放在里面了。并在一面打了一个洞，如此ethernet 线材及供电线材可以透过来。

步骤4：亚克力盒子

我很幸运找到了一个够透的亚克力盒子，你可以尽可能的简化你的构建。我在与木头盒子相对应的位置钻了一个洞，这样线材就可以轻松的插到灯上。

钻完洞，我用磨砂玻璃喷漆给他罩了一层外衣。一旦射出来盒子里的图形光可见。图像就会清晰的看到。

步骤5：泡沫塑料盒子

我用了一个小薄片的泡沫，并把亚克力盒子的开口按进了泡沫。而后在泡沫中留下一个印记，随后就开始切割。根据泡沫上的印记，讲Arduino放到里面，就构建出镶嵌物的位置了。

步骤6：Arduino代码

以下代码是用于Nike Restock 闹钟的代码。你需要更改代码中的ip地址及mac地址。

/*
 Twitter Client with Strings This sketch connects to Twitter using an Ethernet shield. It parses the XML returned, and looks for this is a tweet You can use the Arduino Ethernet shield, or the Adafruit Ethernet shield, either one will work, as long as it's got a Wiznet Ethernet module on board. This example uses the DHCP routines in the Ethernet library which is part of the Arduino core from version 1.0 beta 1 This example uses the String library, which is part of the Arduino core from version 0019.
