Circuit by, photoelectric sensing, voltage comparison, the motor drive several parts. The luminous tube is projected to the black and white parts with different reflectances, and the received photoresistor resistance changes. LM393 compare the size of two photosensitive resistors, control the operation of the motor on both sides, thereby correcting the direction of the car to ensure that the car along the black track forward, the motor is equipped with slowdown device, please hand vigorously rotation to prevent damage.   Tracing the car after the overall effect of the assembly diagram:   Tracing car motherboard assembly diagram(Store warm tips every buyer friends: to provide the motherboard assembly map is the real manufacturers, is the real factory direct sales, in order to really provide after-sale technical services, please do not buy cottage products, so as not to be fooled!)
