Smart tracking car kit

Model: D2-1.
This kit includes all the necessary elements to build a car capable of following a 15mm black line on a white background. Its circuit is a typical application of the LM393 comparator with which the signals delivered by two photocells are analyzed. It is not programmable, its intelligence is in the circuit itself. A soldering iron is necessary to mount the electronic components on the board. Ideal for welding practices.
