D2-1 DIY Intelligent Tracking Line Smart Car

D2-1 DIY Kit Intelligent Tracking Line Smart Car
Fun little project. Not too complicated and the instructions provided are very clear and easy to follow.
A good set for learning soldering and the basics of mechanics.
There is a 15 mm wide black runway in the white field. The tracking car can drive along the black runway automatically. No matter how the runway is bent, the car can be driven automatically. We all know that reflectivity is different when the light sources to the white objects and black objects. Here we use a red light source. The light is reflected through the ground to the photoresistor. Detecting the resistance of the photosensitive resistor can determine whether the car is driving in the white area. If the detection is black runway, then the car to change the direction of driving and the motor will slow down or even stop and the Red LED OFF on the PCB's front side. Drive the car in the opposite direction so that the car is always running along the runway.
