Projects by Program Complexity

If you want to learn more about programming using the NXT-G programming system, then you can open and study the programs for these projects after building and using the project.  You will see examples of several of the NXT-G programming techniques in action including Loops, Switches, Data Wires, Sequence Beams, Logic/Range/Compare, Math, and Variables.  The more complex programs use many or all of these, so start with the easy ones and work your way up.
