We build a car in which we can track the motion of any unit, by a digital circuit. In the process of assembly, we could not only familiar with mechanical principles but gradually can learn photocell and voltage comparator, motor drive circuits, etc related electronic knowledge as well as assembly and disassembly skill.

The novelty of this product is that it has both digital output control automatic speed regulation and self-sensing control devices. Control of the motor is achieved by following the principle of Hall's matching transformer and the electromagnetic transmitter.

It consists of a microcomputer controller and particular single-chip microcomputer controlled, integrated CE, I/C, and PWM ICs in one module assembly. This chip can be used as a stand-alone or be added to another system as well as being powered from any DC power supply as long as it meets rail voltage specification

Light-sensitive resistance is sensitive to the external light intensity, the stronger the outside light photosensitive resistance is small, the light-sensitive resistance will be an obvious difference for subsequent circuit control.
