The 'Switch' block can be used to check if the rotation sensor has turned past a specified position in a specified direction. Specifying below zero degrees in the Compare section will separate the negative from the positive angles. In this example, the switch block checks if the rotation sensor is turned below zero degrees. If it is (true, or check mark), the screen will display the text “negative”; otherwise, it will display “positive”. This program also displays the angle, in degrees, of the rotation sensor. SES    :    : * : * :   What are some possible uses for the NXT rotation sensor? How do I program it with NXT-G? 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? How do you program in ROBOLAB with an NXT rotation sensor in ports A-C? What is the difference between the Motor block and the Move block? My car won't move when I push Run on the RCX.
