DIY Kit Intelligent Tracking Line Smart Car
There is a 16 mm wide black runway in the white field. Our 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 the reflectivity is different when the light source to the white objects and black objects. Here we use a red light source. The light is reflected through the ground to the photoresistor. By detecting the resistance of the photosensitive resistor can determine whether the car is driving in the white area. If the detection is a black runway, then the car to change the direction of driving and motor will slow down or even stop and Red LED OFF on PCB front side. Drive the car in the opposite direction so that the car is always running along the runway.

I received everything, thanks to the store. the delivery is fast, everything is intact. we will write in addition.
Perfecto. I ordered two more for my kids. On the other hand, black markers or black insulating canvas are needed to draw the routes… We’re a fan of it here!
Works! The child is happy. One motor confused polarity and therefore did not immediately earn.
Exactly what I ordered. Timely shipping to the United States. Great price. Good quality.
Unexpected that it will come so quickly, thank you very much to the store. everything is clear.
Everything as described. Excellent store’s communication. Full recommended.
Everything works. The son is delighted. Definitely recommend. Tip: check the polarity of the engines-the wheels should spin in one direction, otherwise the robot goes crazy. Also, substring resistors can adjust the sensitivity of sensors.
Works well… the sticky tape is not very good but a little glue and it is fine.
Set without re-order. Everything worked right away. The child is delighted. On the assembly everything is clear from chinese paper and board. Thank You
The store sent everything quickly. March 4 ordered, 16 received. Completeness has not yet checked, as it takes time to assemble. I’ll sign it later. And so it looks good.
