D2-1 Intelligent Line Tracking Car Kit
This kit introduces quite a few electronic principles, its fun and not difficult to build. This is a self-build DIY smart tracking robot car kit. It is an introductory electronic kit designed to help kids, electronic enthusiasts, and novices learn about basic electronic knowledge like soldering and simple circuits(photoelectric sensor circuit, voltage comparator, motor driving,ir sensors etc.) The smart kit is designed based on the principle of infrared sensor and light reflectivity difference when the light emitting on the white and black items
The manual included in the kit is not in English. Please download the English manual here: D2-1 Intelligent Tracking Car Instructions
Line Tracking Car Kit Power requirements: 3V (two AA batteries) (package does not include batteries)
This kit must be self-assembled. All parts needed are included.
It is a fun project. Only issue is that i found when soldering, some of the soldering points lifted and broke away from the tracks on the main board. The wheels are very flimsy and the screws too short for connecting to the shaft of the motor.
Also once again the instructions is in Chinese and this makes the building of the project a bit challenging. Entry level users might find this project tricky. It would be nice if there was an explanation on the working of the circuit.
