Description: I first look for a track car, the procedure is very simple, only a dozen lines. Mainly used two external interrupt. Is taking the black white line trajectory. Schematic of the sensor part, we can find on the Internet. The principle is if the sensor is on a black background, the output high. If the white line is detected, the output low, two sensors to the microcontroller P32, P33 are. Can be achieved through the white trajectory function. Sensor I used is the ST168. ST178
