Courses & Lessons

A course is an ordered set of modules (lessons). The library at learn.devoltapp.com/library shows each published course with its difficulty, estimated time, and module count, plus a Continue card and progress bars so you can pick up where you left off.

The courses

Introduction to Electronics (Hobby)

The official beginner course — ten modules, roughly two hours total, all free. It starts at the breadboard and builds up through real circuits:

1. Breadboards and how rows connect
2. A single LED with a current-limiting resistor
3. A pushbutton input
4. A latching switch
5. LEDs in parallel
6. Fading an LED with a capacitor
7. A transistor as a switch
8. An RC / transistor delay
9. A traffic-light sequence
10. A 555 one-shot

Logic Gates (Pro)

An intermediate course — eight modules, around two hours — covering digital logic with real 74-series ICs: logic levels, NOT, AND, OR, NAND, XOR, a half-adder capstone, and a NAND-latch bonus. Logic Gates is part of the Pro library.

Inside a lesson

A lesson fills the screen with a circuit canvas and a floating lesson guide. The guide holds the instructions and the objectives checklist with a progress bar. Along the bottom you get four tools:

• Lesson — the brief and objectives.
• Probe — a multimeter-style readout of any node.
• Parts — the parts palette, filtered to just what the lesson needs.
• Scope — the oscilloscope, for lessons that involve changing signals.

How objectives are checked

Objectives are evaluated continuously against your live circuit — there is no “submit” button for them. A few kinds of objective exist:

• State — a voltage, current, or LED being lit right now.
• Topology — how things are wired together.
• Sequence — something happening over time, such as a blink.
• Dynamic — a time-based behaviour, such as a fade or a delay.

Once an objective passes it stays passed even if you keep tinkering, and your progress is saved to your account. If a save ever fails, the lesson shows a “Progress not saved — retrying” notice and keeps trying.

Finishing and moving on

When every objective passes, the guide’s button becomes Next module (or Finish course on the last one). Some modules carry your finished circuit forward as the starting point for the next, so each lesson builds on the last.

The AI tutor

Stuck on a step? Press Get an AI hint in the lesson guide. The tutor is Socratic — it asks a leading question or points you at the next thing to try in a sentence or two, and deliberately will not hand you the finished circuit. Hints are ephemeral: de:volt does not store your prompts.

The tutor is separate from the simulator’s AI assistant, which edits circuits. Students who reach Learn through a class join code do not get the AI tutor — if the tutor is unavailable, the lesson falls back to its built-in written hints.
