Smart Tracking Car DIY Accessories Kit Smart Robot Car Kit Kids DIY Electronics Education Competition

Mechanisms: This smart tracking car DIY kit can help you be familiar with mechanisms and learn about photoelectric sensor, voltage comparator, motor drive circuit and other related electronic knowledge in the process of assembling Photosensitive Resistor: Photosensitive resistor can detect the strength of the external light, the stronger the outside light, the smaller resistance will be. When red LED light is projected onto a white area and a black area, due to different reflective rate Accuracy Voltage Comparator: LM393 is dual channel voltage comparator integrated circuit, composed of two independent accuracy voltage comparator. It is used to compare two input voltage, and change output voltage according to input voltage Reduction Gear: Special made motor has reduction gear and greatly reduces difficulty, which is very suitable for use Resistance Appears Imbalance: LM393 compare two photosensitive resistance, and stop one side motor when the resistance appears imbalance, the other side motor rotate faster to get car back to the right direction
