Ohmie: Learn Electronics

Pass circuits. 3 minutes a day.

Ohmie teaches electronics the way you'd learn a language: short, game-like lessons you actually solve, not paragraphs you skim.

REAL PRACTICE, NOT PASSIVE READING • Live circuit sims — stack battery cells, dim an LED, watch current respond to resistance • Build schematics by dragging real components into place • Decode resistor color bands, spot the broken circuit, order the steps • Miss a question? It comes back in Practice until it sticks — that's the method, not a penalty.

LEARN THE FULL PATH • Circuits — charge, current, voltage, Ohm's law, series & parallel, your first LED circuit • Op-amps, components, transistors, digital logic, power • Embedded systems — GPIO, PWM, ADC, interrupts, serial protocols • Robotics — sensors, motors, PID control, build a line-following racer

MOMENTUM THAT FORGIVES XP, streaks, daily quests, and a mascot named Ohmie who's on your side. Streaks are forgiving — life happens.

No ads. Your progress stays on your device.
