                  Smart cars are also interesting and involve the mechanical structure, electronic foundation, sensor principle, automatic control and even single-chip programming and other subject knowledge, which can greatly improve the ability of hands-on practice.
                  The smart car is also a good hardware platform that can be converted into a tracking car, a fire fighting robot, a soccer robot, and an obstacle avoidance robot.


                  ● Can travel along a black track about 15mm wide
                  ● The circuit consists of several parts, photoelectric sensing, voltage comparison, and motor drive.
                  ● The reflectance of the light-emitting tube projected to the black and white portions is different, and the resistance of the received photoresistor changes.
                  ● LM393 compares the size of two photo-resistors and controls the operation of the motors on both sides, thus correcting the direction of the car and ensuring that the car moves along the black track.
                  ● The motor is equipped with a speed reducer. Do not rotate it vigorously to prevent damage.
                  ● The fighter kit has a battery compartment for two AA batteries.
