我的项目是关于通过网络服务器解锁和锁门。但是我的arduino程序有一些问题。我是新的arduino程序，这是我的程序。我无法解决我的arduino程序错误
可以帮我解决这个问题吗？
/*
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)

为了您的信息，这是原来的LED程序，但我改变它。
这是错误，当我编译了一个程序
