Questions tagged [nxt]

The NXT tag should be used when asking question about programming in the NXT 1.0 or 2.0 environment, or about programming the NXT 1.0/2.0 controller using other methods than the language/environment provided by LEGO.

NXT is the previous version of the LEGO Mindstorms robotics kit. NXT includes the microcontroller and the software to program it.

The NXT software was developed for LEGO by National Instruments (makers of LabView) and is a graphical, drag-and-drop programming environment.

NXT environment allows interaction with a wide range of sensors available for the controller as well as interacting with up to 3 motors per controller.
