Function Description:
In the white field there is a 16 mm wide black runway, our track trolley can automatically travel along the black runway, no matter how the runway is bent trolley can automatically travel is really amazing! We know that the reflectivity of the light source is different when it is shot to white objects and black objects, we Here we use red LED as the light source, the light is reflected through the ground to the photo Through the detection of the photoresistor resistance change can determine whether the car is traveling If it detects a black runway, it means that the trolley runs off, and the motor on this side will slow down or even stop the green LED on this side. LED goes out, driving the car in the opposite direction. In this way, the car can always follow the runway.
