The configuration panel allows you to choose how the block makes the decision.   The program attached, logic.rbt, is a good example of how the logic button can be used to create a remote control. This program makes a car run whenever touch sensors 1 and 2 are simultaneously pressed.    :    : * : * :   Are there any tricks for using the logic output from the rotation sensor block in NXT-G? My green data wires always turn grey. What might I be doing wrong? 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? 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? What is the Variable block for? What is the NXT-G Compare block for? logic.rbt (311,710 )
