Rooms ask you questions. Labs hand you the parts.
Build something, test it, break it, and only move on once it works. Nothing is marked by comparing you to a reference answer — your circuit is run against every possible input, so anything that genuinely works, works.
- 1Close the circuit
- 2Which way round
- 3Pick the resistor
- 4Ohm's law
- 5Two at once
- 6Why isn't it working
- 7A switch is a gap
- 8A pin is a switch

Before you build a circuit
The handful of ideas that make the Electronics bench lab make sense: what voltage, current and resistance actually are, why an LED needs a resistor, and how Ohm's law ties them together. Ten minutes.

LEGv8: Machine Code, Registers & Subroutines
The machine code trips up more students than the assembly itself. Hex/binary conversion, MOVZ vs MOVK, immediate-value limits, and translating real bit patterns to assembly and back — practice built for 1DT301's labs and exam.

RPi Pico: Interrupts, GPIO & Computer Architecture
Polling vs interrupts, the IRQ vector, PC/LR/SP, and the buses that move data around a CPU — the theory half of 1DT301's Pico labs, the part that is easy to skip past while your LEDs are blinking.

Before you write a program
The ideas the Program a siege lab assumes: what an instruction is, why input() never gives you a number, what a loop actually repeats, and the difference between printing an answer and returning one. Ten minutes.

Before you build a CPU
The handful of ideas that make the Build a CPU lab make sense: what a truth table is, how counting works with nothing but on and off, and why adding two bits needs two digits. Ten minutes.

Generative Engine Optimization: Getting Found by AI Search
"SEO Fundamentals: How Pages Get Found" covered how a page gets crawled and ranked. This is the 2026 half of the same subject — how a page earns a citation inside an AI-generated answer instead of a blue link on a results page.
