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. Lessons are read aloud, so your eyes stay on the circuit. REAL PRACTICE • 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 • Electronics: charge, current, voltage, Ohm's law, series and parallel, capacitors, power, analog, then transistors, logic gates and an 8-bit computer you can run, pause and step through • Embedded systems: GPIO, timers, PWM, ADC, interrupts, serial protocols, build a device • Robotics: sensors, motors, PID control, build a line-following racer • PCB design: schematics, layout, routing, production • Programming: Python, and C++ for Arduino EXPLORE OHMIE WORLD Walk into Copper Town, take on the trainers in the forest, wire the town's circuit on a breadboard, and face other learners in the Arena. MOMENTUM THAT FORGIVES XP, streaks, daily quests, 30 badges to earn, skins to unlock, leaderboards, and a mascot named Ohmie who reacts to every answer and is on your side. Streaks are forgiving. Life happens. Stuck? Ask Ohmie and get a hint in plain words. No ads. Learn in English, Spanish or German. Sign in to keep your progress across devices.
