WWZMDiB-DIY Learning Kit Introductory Electronic Components Kit Birthday Gift Desktop Decorations(Fun DIY Soldering Kit,D2-1 Intelligent Tracking Line Smart Car) ?D2-1 Intelligent Tracking Line Smart Car?Intelligent Tracking Line Smart Car vivid and interesting also involves mechanical structure, electronic foundation, sensor principle, automatic control and Welding Technology even microcontroller programming and many other discipline knowledge Power supply voltage?:3V DC ?Working principle?:LM393 is always comparing the size of the two photoresistors, when there is an imbalance (such as one side of the pressure black runway) immediately control one side of the motor to stop, the other side of the motor to accelerate the rotation, so that the car to correct the direction, back to the correct direction, the whole process is a closed-loop control, so it can be fast and sensitive control. ?Track Experiment Test?: It can follow the black runway to walk automatically and identify the direction automatically,Unleash your creativity by designing intricate runways directly on the ground using 1.5 to 2.0 cm of black electrical tape. ? Easy Assembly?: The connection that was clearly mapped and labeled on the board makes it easy to assemble. ?Wholesale business?:We have been engaged in the wholesale and retail business of electronic related products for a long time. The larger the amount, the better the price.
