يعرض هذا البحث كيفية تصميم و تنفيذ دارة للتحكم بحركة لوح كهروضوئي للحصول على أعظم مردود ممكن، و ذلك عن طريق تصميم نظام مكون من دمج عدة طرق من التحكم مع بعضها البعض، و يتم التصميم من خلال تشكيل نظام موحد ندمج فيه التحكم بواسطة حساسات الضوء من جهة و التحكم عن طريق قاعدة بيانات من جهة أخرى بالإضافة الى مقارنة زاوية اللوح الكهروضوئي في كلا الطريقتين.
تم تصميم الدارة المقترحة و إجراء المحاكاة لها و تنفيذها بنموذج مصغر يحاكي الواقع، و مناقشة النتائج و ذلك لتبيان الفائدة و الهدف من النظام المقترح استخدامه و ذلك بواسطة المتحكم الصغري Programmable Interface Controller(PIC).
This paper shows how to design and implement control circuit in the movement of
pv board to reach to maximal possible output, by designing a system to integrate several
methods of of control with each other. During this work, we will design through formation
a unified system combine control by light sensors, and control via data base on the other
hand. In addition to compare pv angle in both ways. The proposed circuit designed,
conduct a simulation, and implementation a miniature model simulates reality, and
discussed the result to to conflict the advantage and the goal of using the proposed system.
All that by using micro controller (PIC).

The weigh feeders constitute an essential part of any production facility, where its
control and supervision system is one of the important things that should be characterized
by precision and reliability.
