舵机控制程序，可供参考，按键后，旋转一个角度。-Servo control procedures available, buttons, rotate at an angle.

在LabvIEW中对数字表盘上的数字进行定位，可旋转很大角度精确定位-In LabvIEW the figures on the dial of the digital positioning, precise positioning of rotating large angle

能够使用arduino uno r3来通过步进电机控制器，实现步进电机旋转角度及旋转速度的控制(Arduino uno R3 can be used to control the rotation angle and speed of stepping motor by stepping motor controller.)
