说明：  Arduino控制板对舵机进行PID参数设置的程序 ，对舵机进行PID参数设计，搭载二自由度云台，因此设置了两个方向的PID参数
(The Arduino control board carries on the PID parameter setting program to the steering gear, carries on the PID parameter design to the steering gear, carries two degrees of freedom pan head, therefore has set two direction PID parameter)
