My green data wires always turn grey. What might I be doing wrong? 19th of April, 2010 (1 ) 100% 0% Example: There are two connections under the Rotation Sensor block. One is logical (true/false) and the other is numeric. As the example shows, wiring logical to logical leaves a green wire; wiring logical to numeric leaves a grey wire. A grey wire indicates a badly connected wire. All of the other settings on the rotation sensor block are important. Set them incorrectly and the logic block will not work as expected.    :    : * : * :   What is the NXT-G Logic block for? Why would I need to use logic inputs and outputs in NXT-G? What is an example of a program that uses logic inputs and outputs? What are some possible uses for the NXT rotation sensor? How do I program it with NXT-G? Can the NXT rotation sensor sense negative and positive rotation (counterclockwise and clockwise)? How can I do I combine the values of different sensors in NXT-G? For example, how could I program the motors to start only when there is combination of a loud sound AND a bright light?
