![]() For those students enrolled in our courses, please document your creation journeys in your prototyping journals and attempt to answer and reflection on posed questions. Please build with us to advance your understanding and skillset-the best way to learn is by doing!. Materialsįor this lesson, you will need the following materials. See our Introduction to Electronics series, specifically the lesson on Voltage, Current, and Resistance. A more accurate visualization would show that electrons are already distributed throughout a wire before a voltage is applied. This visualization is a coarse abstraction designed to emphasize the direction of current flow. Instead, our goal is to build some initial familiarity with Arduino hardware and connecting components to Arduino pins before we introduce programming, which we do in the next lesson.įigure The movement of current in the circuit is illustrated by the animated yellow circles.
