DIY Kit Intelligent D2-1 Patrol Tracking Car

LM393 chip at any time compared with the size of the two photosensitive resistors, when there is unbalanced (such as the pressure side of the black runway) immediately control the side of the motor stop, the other side of the motor to accelerate rotation, so that the direction of correction car to restore to the right Direction, the whole process is a closed-loop control, it can quickly and sensitive control.

• With red or green LED as a light source, the light reflected through the ground to the photosensitive resistor by detecting the photosensitive resistance change can determine whether the car traveling in the white area
• If a black runway is detected, it indicates that the car is running. This side of the motor will decelerate or even stop. The green LED will go out and drive the car in the opposite direction, so the car will always run along the runway.
• Can also homemade runway, with a width of about 16mm black electrician tape, put on the ground any shape.
