我的項目是關於通過網絡服務器解鎖和鎖門。但是我的arduino程序有一些問題。我是新的arduino程序,這是我的程序。我無法解決我的arduino程序錯誤

可以幫我解決這個問題嗎?

/* 
    Web Server 

A simple web server that shows the value of the analog input pins. 
using an Arduino Wiznet Ethernet shield. 

Circuit: 
* Ethernet shield attached to pins 10, 11, 12, 13 
* Analog inputs attached to pins A0 through A5 (optional)

爲了您的信息,這是原來的LED程序,但我改變它。

這是錯誤,當我編譯了一個程序
