LM393 comparator integrated circuit
DC motor with gear reduction gear
This is photosensitive resistance, it can detecting the external light intensity, the stronger the outside light photosensitive resistor resistance is small, the outside light weaker resistance bigger when the red LED light projected onto a white and black runway because reflection rate is different, the resistance value of the photosensitive resistance will occur obvious difference for subsequent circuit control
LM393 to compare two photosensitive resistance, when the imbalance (e.g. side pressure runway black) immediately control side of the motor stops rotating, the other side of the motor rotational acceleration, so that the car modification direction, return to the correct direction, the whole process is a closed loop control therefore, rapid and sensitive control.
