Line Following Car Soldering Kit

Learn soldering and robotics in one hands-on project with the D2-1 DIY Line-Following Robot Car Kit. This classic smart-car follows a black line automatically using a pair of infrared sensors and an on-board control circuit. Two gear motors drive the wheels while adjustable trim potentiometers let you fine-tune tracking sensitivity for different tracks and lighting conditions.

The kit is sold as loose components for you to assemble. A printed paper manual is included with a full parts list, schematic diagram and step-by-step installation guide-and there's even a simple practice track printed on the back so you can start testing immediately after assembly. Ideal for STEM classrooms, maker clubs and first-time solderers.
