상품 특징

• 【Product Labeling】:This is a DIY electronic kit, not a final product that needs to be soldered by your own hands.Smart tracking car can discriminate the directionautomatically that it can run freely along the blacktracking line. You can also use the1.5∼2.0 cm blackelectrical tape directly on the ground to design thecomplex runway. It would be even more fun!
• 【Product Principle】:The principle is that the reflectance of the light tube projected to the black and white parts is different, and the light intensity reflected to the receiving surface of the photoresistor is different, resulting in a change in the resistive value of the photoresistor. The LM393 compares the size of the two photoresistors and controls the operation of the motors on both sides, so as to correct the direction of the trolley and ensure that the trolley moves along the black trajectory.
• 【Product Features】：Automatic tracking can drive automatically along the black runway, no matter how the runway is curved, the car can drive automatically. If you want to make your own track, the amplitude of the track turn should not be too large.
• 【Easy Assembly】: Clearly mapped and marked connections on the board make it easy to assemble. You can refer to the markings on the PCB board to solder each component. If it doesn't work after welding, please contact us for support.
• 【Product Manual】The D2-5 Intelligent trajectory trolley kit comes with a paper manual that includes soldering steps and techniques, making your soldering process very simple and providing you with a great welding experience.
