Features: This smart tracking car DIY kit can help you be familiar with mechanisms theory and learn about photoelectric sensor, voltage comparator, motor drive circuit and other related electronic knowledge in the process of assembling. 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, photosensitive resistance will be different, which is convenient for follow-up circuit controlling. LM393 is dual-channel voltage comparator integrated circuit, composed of two independent voltage comparator. It is used to compare two input voltage, and change output voltage according to input voltage. Special made motor has reduction gear and greatly reduces difficulty, which is very suitable for use. 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. The whole process is a closed-hoop control, so it can control quickly and sensitively.

Package Includes: 1 x Smart Car DIY Set (Disassembled Parts)
