I am going to build a robot car which can perform line tracking. And I am going to share with all of you how I will make it.
This line tracking robot car was built base on the prototype mentioned in the previous knowledge item.
A photodiode and a white color LED could be used to build a circuit to sense the line for the line tracking robot car.
In Arduino Leonardo Board, there is a fan out current limit for an I/O port pin for Arduino board that is about 40mA, which is not enough for a DC motor running with load.
