我目前正参与一个项目，该项目需要通过wifi独立开启/关闭4个LED和1个步进电机。
提到我使用Uno r3，官方Wifi防护罩和官方电机防护罩。
我有4个LED工作在A2-A5引脚或我的代码引脚（16-19）中，保留所有数字引脚，并将我的步进电机设置到引脚9,8,6,5。当我转到ip地址时，我可以独立地关闭/打开每个LED，但是使用步进电机，它可以抖动，也可以不移动或者根本不移动。
我已将我的代码发布到目前为止，非常感谢任何帮助或建议。感谢

WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.
This sketch will print the IP address of your WiFi Shield (once connected)
to the Serial monitor. From there, you can open that address in a web browser
to turn on and off the LED on pin 9.
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
Circuit:
* WiFi shield attached
* LED attached to pin 9
