Unit: YSMClass: Clone of Variables and Logic

This unit begins with introduction of the programming concept of variables, as students learn to create an manipulate variables in the Lego Mindstorms NXT-G program, through lessons from the "NXT Video Trainer 2.0" product from Carnegie Mellon University's Robotics Academy. A lesson on Boolean Logic is then followed by an advanced lesson on controlling loops with a logic variable. The unit wraps up with some advanced programming challenges.
