基于LabVIEW的步进电机控制器的设计，通过上位机与下位机通信并控制步进电机转动-The design of the stepper motor controller based on LabVIEW, through the host computer and the next bit machine communication and control stepper motor rotation

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.)
