Confirm the work voltages exceed limit voltage then lead sensor pin to burn.
确认工作电压超过限额的电压并引导传感器销，燃烧。
Abnormal image is caused by sensor pin (VREFH) open, from the picture, found it is burned.
异常引起的图像传感器销钉(VREFH)打开，从图上，找到它了。
Focusing on the pin number, it then goes into a switch structure that takes a different action depending on which sensor is connected to the pin.
以管脚编号为中心，然后再进入到一个switch结构，根据连接到此管脚的传感器来采取不同的措施。
You then have analog pins 3 to 6 available for sensor input; assuming pins 1 and 2 are reserved for use by the Ethernet shield (see Resources for more about pin usage).
模拟的插脚3到6可供传感器输入使用；假设插脚1和2保留给Ethernetshield使用(查看参考资料，以了解有关插脚使用的更多信息)。
