This unit delves into some of the underlying technologies of robotics in general, and then explores each within the context of the LEGO MINDSTORMS Education Core Set. First, electrical circuits are covered followed by exercises using the EV3 as a circuit and demonstrating the function of each of the EV3 sensors in Port View (equivalent of View Mode for NXT). Second, the topic of computers is covered, including both the history (Moore's Law) and parts of computers. There is a Jeopardy Game that covers all the Lessons in this Unit in the Unit Level Assessment.
