Hallo! I try to write a class for legOS in c++. The constructor should get parameters for the used ports for a motor and two sensors, which are private components of the class. Then the contructor should assign these given ports to the private motor (...) (23 years ago, 4-Apr-01, to lugnet.robotics.rcx.legos)

Hi, I've got a way to use a Rotation sensor and a light sensor on the same input, and get reliable, useful values from both. This is for real. See : (URL) was interested if anyone else has done this. Enjoy everyone. Mike Amy (23 years ago, 2-Apr-01, to lugnet.robotics.rcx.legos)
