Product Features
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.

Product Description
Brief introduction of working principle

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.

With the purpose of simplifying the complex principle, we first make a by digital circuit to control the intelligent tracking car, in the assembly process, we could not only familiar with the mechanical principle can gradually learn to: photoelectric sensor, a voltage comparator, a motor drive circuit, and other related electronic knowledge.

Photosensitive resistance device

Package included: 1 pcsx In D2-1 line patrol car parts production of Electronic Science and technology DIY telligent tracking car kit (Due to the shipping way is not allow,so we not included the battery, thanks for your well understanding! )
