Electronics guides

Short, practical explanations that match what you can try in the simulator.

How a breadboard works

Rows, columns, the centre gap and power rails, explained with a first LED circuit.

Logic gates and truth tables

NOT, AND, OR, NAND, NOR and XOR, the matching 74xx chips and how to wire them.

Circuit simulation explained

DC steady state, RC transients, LED and transistor behaviour, and op-amp basics.

Classroom and self-study ideas

A suggested order for the built-in labs, plus tips for teachers and learners.

Quick start in four steps

  1. Open the lab and tap Battery in the bottom toolbar, then tap two holes on the board.
  2. Add a Resistor and an LED, then close the loop with a Wire.
  3. Press Run. Voltage, current and power appear at the top.
  4. Prefer guidance? Tap Labs to load a guided practical in one tap.
