Device Notes Index
This note set runs in parallel with the lesson notes. Instead of being organised by lesson, these sheets are organised by device or subsystem.
Use them when students ask questions like:
- What is this part for?
- Who made it or where did it come from?
- How does it talk to the microcontroller?
- Why did engineers choose this device?
- What are the limits and tradeoffs?

- Pair the Breadboard note with every layout and wiring activity.
Teaching Tip
These sheets are best used as short sidebars, reference notes, or extension tasks. They are not meant to replace the lesson flow. They help students see each module as a real piece of engineering with its own history, rules, and communication method.
