System for solar orientation using common electronic parts

The solar orientation circuit uses a comparator with window control that maintains engine idle as long as the two LDR`s (photoresist) are subjected to the same illumination. In this case, half the voltage is applied to the noninverting input of A1 and A2`s inverting input. When the sun`s position changes, lighting affecting LDR R1 and R2 sites is

different, the comparator input voltage window is not half the supply voltage, the comparator output so that the engine generates information for the purposes of direct or rotate counterclockwise counterclockwise.
