D2-1 Smart Tracking Car Kits Photosensitive LM393 for DIY Robot ElectricToys
LM393 compares the value of the two photoresistors at any time. When there is an imbalance (for example, one side presses the black track), the motor stops immediately at one side and the motor rotates at the other side, so that the carriage corrects the direction and returns to the correct direction. Above, the whole process is a closed-loop control, so it can be quickly and sensitively controlled.
On the back of the assembly instructions is an easy runway for the tracking car.
Customers can also use the 1.5~2.0 cm black electrical tape directly on the ground to design the complex runway.
Note: the item is not include batteries.
