MiOYOOW Line Following Robot Car Kit, Beginners Smart Car Soldering Practice Kit STEM Educational Electronics Soldering Projects for School and Home Learning

• ✔【School Science Project】: Smart DIY robot car is the most widely used in school for helping students to learn about the soldering project knowledge of mechanical structure, electronic basis skills, the principle of sensor, automatic control, soldering skill and so on.
• ✔【Its Principle】: As the light reflectivity is difererent when the light is emitting on the white and black items. It uses the photoresistance resistance to tell the smart car is on the right way or not. Smart tracking car can discriminate the direction automatically that it can run freely along the black tracking line.
• ✔【Design Your Runway】: You can also use the 1.5~2.0 cm black electrical tape directly on the ground to design the complex runway. It would be even more fun! This educational kit is perfect for holiday gifting and promotes valuable STEM skills!
• ✔【Easy Assembly】: This smart car solder practice kit is easy to build and the principle is simple. The connection that was clearly mapped and labeled on the PCB board. It's much easier to assemble which is great for students, teenagers, beginners and DIY hobbyists.
• ✔【English Manual】: We provide paper English instruction come with the product. You can scan the QR code in the last picture to get PDF manual. You can also download the Installation Manual on the Product Page Named "Technical Specification" Section (Due To Character Limit).
