Classroom and self-study ideas

A path from your first resistor to op-amps and adders.

A suggested lab order

Ohm’s law, series and parallel resistors — build confidence reading voltage and current.
Voltage divider — see how two resistors share a supply.
LED with a current-limit resistor — apply Ohm’s law to a real design question.
Diode rectifier check and transistor as a switch — meet one-way and controlled conduction.
RC charging circuit — connect τ = R × C to what you see.
Verify the gates (NOT, NAND, NOR, AND, OR, XOR) — complete each truth table.
Build NOT, AND and OR from NAND — learn why NAND is universal.
Adders and more — half adder, full adder, subtractor, comparator, multiplexer and parity.
Op-amp circuits — follower, inverting, non-inverting, summer, difference, comparator and integrator.

Project a practical on a screen, predict the reading as a class, then press Run.
Ask students to break a circuit on purpose (remove the resistor, reverse the LED) and explain the warning.
Use “share as image” so students can submit a picture of their finished board.
Set a truth table as a challenge: students must tick every row in the verify practicals.

Predict before you press Run — it is the fastest way to find gaps in understanding.
Use the activity timeline to step back through what you changed.
Save circuits to the library and export them as a backup.
Keep notes in the built-in notes folders.
