Don't just build it.
Understand why it works.
Drag in a battery, a resistor, an LED. Wire them up and watch it light up in real time — and if something's wrong, Tinkron tells you why before you ever plug it in. No breadboard, no software, no experience required.
Parts
Selected: LED
Not just a simulator. A reason for every result.
Tinkron doesn't just show you a circuit works or doesn't — it explains why, so you actually understand what you built.
Know Why, Not Just What
Wire an LED without a resistor and Tinkron doesn't just flag it — it runs the actual Ohm's-law math and tells you it'll burn out, and why. Real reasoning, not a red X.
See It Work, Instantly
No breadboard, no guesswork. Wire two parts together and watch current flow in real time — Tinkron tells you if something's wrong before you ever plug it in.
Share Like a Doc
Send a link, not a schematic file. Anyone can open your circuit in the browser, no software to install, no account required to just look.
From idea to working circuit, in one afternoon.
No prior experience needed. Tinkron guides you at every step.
Drag Parts Onto the Canvas
Start from a blank canvas and drag in a battery, a resistor, an LED, or a switch — straight from the parts list. No symbols to memorize.
Watch It Work — or See Why It Doesn't
Wire two pins together and current flows immediately, right in your browser. Forgot a resistor? Tinkron doesn't just flag it — it tells you why an unprotected LED will burn out, before you ever plug one in.
Save It, Show It, Come Back To It
Export a snapshot of what you built, or share a link — anyone can open it in their browser, no software and no account required to just look.
