The stepper motor driver is made with a dedicated integrate circuit. This unit is used to control a photovoltaic panel solar orientation. The orientation angle is dictated by a sensor made of two photodiodes. %K Visual C++ %K stepper motor %K solar orientation %K photovoltaic panel %U http://pubs.ub.ro/dwnl.php?id=JESR201203V18S01A0016
