MIT App Inventor和Arduino以太網LED錯誤1109 URL無效

我開始使用具有以太網和電話的arduino的家庭自動化系統的基礎，該軟件與MIT應用程序發明者一起編程。我一直在玩代碼的教程，並得到了我的LED罰款從本地計算機使用互聯網使用瀏覽器和導航網址192.168.1.10/$1MIT App Inventor和Arduino以太網LED錯誤1109 URL無效

/* thrown together by Randy Sarafan 

Allows you to turn on and off an LED by entering different urls. 

To turn it on: 
http://192.168.1.10/$1 

To turn it off: 
http://192.168.1.10/$2

這個問題我來打開和關閉有移動端的。我創建了麻省理工學院應用發明一個應用程序，應切換IP，而是給了我：

錯誤1109：指定的URL無效：192.168.1.10/$1

林很困惑。我知道這個URL是有效的，因爲我之前已經連接到它。有沒有辦法來重寫或修復它？

English：在AppInventor錯誤「錯誤1109：指定的URL無效：192.168.1.10/$1」您可能忘記將「http：//」放在您的地址中。例如，如果要將地址保存在全局變量或tinyDB中，則應該將http://192.168.1.10/ $ 1 這將是您連接led的地址。

葡萄牙語版本的原因是什麼？ – Tay2510 2015-04-02 05:27:25

您應該在代碼本身指定IP地址。並更改「Ethernet.begin（mac）;」到「Ethernet.begin（mac，ip）;」。

在使用App Inventor進行嘗試之前，您還應該嘗試在瀏覽器中打開網頁以檢查它是否有效。
