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。

技术分享

步骤1:材料

技术分享

 

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

技术分享

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

技术分享

 

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

技术分享

 

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

技术分享

 

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

技术分享

 

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.  

 Circuit:
  * Ethernet shield attached to pins 10, 11, 12, 13

步骤7:完成

技术分享

 

在给Arduino上传程序之后,我把他放到了泡沫垫中,并插上线材。这样就安装好了一个木头盒子。而后在每个角上点一点热熔胶,并盖上亚克力盒子。

剩下的就是在出口那插入电源适配器,并将网线插到路由上。灯会立即点亮,这样就可以开始设置了。接下来就可以等待restock的信息推送了!
