Solar Tracking System

This tracking system is design using only a one small bipolar stepper motor which is found in dumped CD and Arduino. Mechanism used to rotate the panel is same as movement of CD ROM head drive. The power used by this motor is very small and even in home, you can design such a system by your self. Instead of arduino you can even use micro-controller to done this thing. And also this just prototype illustration for rotating mechanism. Further I hope to rotate this panel using hydraulics that can prevent maintenance occurring due to whether conditions. For further details refer the ppt file I have attached with this.
