Learn electronics by building circuits, not memorizing equations.

VoltEzy turns electronics into bite-sized interactive lessons — with simulations, puzzles, fixes, and real projects you actually build.

The problem

Electronics gets hard the moment it starts with formulas.

Textbooks feel abstract

Pages of equations before you ever see a single thing light up.

Breadboards confuse

One wrong row and nothing works — with no hint about why.

Simulators are unguided

Powerful tools, blank canvas, no idea where to begin.

Sparky

VoltEzy gives you guided circuits, instant feedback, and small wins from the very first lesson.

How it works

Learn in small, practical steps.

No lectures. Each node on the path is one idea you try, tune, and keep.

1

Follow a guided path

A clear route from your first LED to real builds — one node at a time.

2/3
2

Learn one idea at a time

Short Funda lessons explain just enough, then get out of your way.

3

Try it in the simulator

Build the circuit, hit run, and watch it respond instantly.

4

Fix, tune, and build

Debug broken circuits and finish each unit with a real mini project.

Lesson types

Every lesson makes you do something.

Five lesson types keep it hands-on — concept, check, tune, fix, build.

Funda
Concept

Learn the idea with simple explanations and circuit previews.

Why LEDs need a resistor
Quiz
Check

Check your understanding with quick, no-pressure questions.

Which way does current flow?
Puzzle
Tune

Tune circuit values until they match a target behavior.

Tune the LED current
Fix
Debug

Debug broken circuits and the mistakes everyone makes.

The LED is reversed
Project
Build

Build useful mini circuits from scratch and keep them.

Build a mini flashlight
Sparky

One example flow: learn the LED → quiz the current → tune it → fix a reversed one → build a flashlight.

FAQ

Questions, answered.

Do I need any electronics experience?
Nope. VoltEzy starts from the very first idea — what voltage and current really are — and builds up one small lesson at a time.
Is this for students or hobbyists?
Both. If you are curious how circuits work and you like learning by doing, VoltEzy was built for you.
Do I need to buy real components?
Not to start. Every lesson runs in the built-in simulator, so you can learn, break things, and rebuild — all on your phone.
How is this different from a circuit simulator?
A simulator hands you a blank canvas. VoltEzy gives you a guided path, instant feedback, and a reason to build each circuit.
Will it work on Android and iOS?
VoltEzy is coming to Android, iOS, and the web. Join the alpha and tell us which one you want first.
Can I use it to learn practical circuits?
That is the whole point. You finish units by building real things — like a mini flashlight — not by memorizing formulas.
