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* 热胶* 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。 p/*br 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.
