Learn electrical engineering by lighting things up.

Bite-sized lessons, a real circuit simulator and instant feedback. lEEd adapts to you, from first-time tinkerer to EE senior.

Try it · live simulation 9 V
+373 Ω18.8 mA

Glowing safely. That’s Ohm’s law at work!

Bite-sized lessons

Short, friendly screens with clear diagrams. Five minutes is enough to learn something real.

A real simulator

Drag parts onto the board, wire them up and press Run. Watch currents flow and LEDs glow, or burn out.

Instant feedback

Every challenge checks your actual circuit and gives specific hints, so you learn from every attempt.

A path that fits you

Tell Pip your goals and where you are. A quick placement test lets you skip what you already know, so seniors aren’t stuck on Ohm’s law and beginners never feel lost.
