As a part of the introduction to the students' course kits, the instructor introduces each component alongside their respective card. Using a document camera feed, the parts and card setups were transmitted via Zoom.
Zach could quickly highlight general functionality and offer comparative visual depiction, and then flip over the card to show a high-level schematic depiction and low-level terminal connections.
"The system of schematic symbology became much easier to refer to, and manipulate, through use of the cards. I was also able to, in a similar level of abstraction, build up general ideas of how circuits are properly constructed, by using multiple cards alongside each other to show, for instance, that a stepper motor needs to be interfaced with the Arduino via a stepper motor driver; I just put the card in between the two to demonstrate how that would work." - Zach, instructor of 99-355
