Control technique for unipolar and bipolar step motor using Arduino and LabVIEW

In this paper we aim to propose a control technique using low-cost Arduino Board and the LabVIEW software. Control techniques were developed for both typologies of permanent magnet stepper motors, respectively unipolar stepper motor and bipolar stepper motor. This solution is addressed to situations were rapid prototyping and accurate control is needed and at a low cost. A power driver module for the bipolar motor was developed as well. Original optimization method for improving the resolution of the bipolar stepper motor by using the microstepping control technique is well adapted for our application.
