DIY line Tracking Robot Smart Car kit

Working principle
Chip lm393 compared the resistor value, when there is an imbalance, the chip will control one motor to stop, while other motor accelerate rotation, in this case, the car can correct direction. The whole process is closed-loop control, so it can be quickly controleed
