White line Flower

Here is simple and low-cost electronic circuit project for White line Flower Circuit.  This circuit will be used for a toy automotive to follow a white line. The motor is either a 3v sort with gearing to steer the automotive or a rotary actuator or a servo motor.

White line Flower Circuit Diagram:

When equal lightweight is detected by the photo resistors the voltage on the base of the primary transistor are mid rail and the circuit is adjusted via the 2k2 pot that the motor doesn't receive any voltage. When one in all the LDR's receives a lot of (or less) lightweight, the motor is activated. and also the same thing happens when the other LDR receives less or more light.
