[求助] 用arduino接受新浪微博提醒
我想做一个用arduino来接受新浪微博消息提醒的东西打算给arduino用wifi连接互联网
不知道有没有人见过或者尝试过类似的，想了解下是否可行 同求。。。。。。 貌似看过人家做过。。。。。。用网络模块+新浪的api 这个我有计划。做完鱼缸控制器后，准备做个类似的应用，信息电子钟。用12864显示个天气预报什么的。
思路先沟通下，用php做个信息抓取工具，输出成arduino能接受的格式。然后arduino 直接读取，显示。 thomas 发表于 2012-4-4 22:36 static/image/common/back.gif

思路先 ...
想法很好嘛，赞一个。 新浪微博的app有一个简单的。可以参考一下 jackiesue2005 发表于 2012-4-8 14:16 static/image/common/back.gif

请问具体是哪个？ 找到一个tt的

我最近也在计划做这个，核心应该就是用arduino来做WebClient，然后取得服务器端反回的信息。
