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. Lessons are read aloud, so your eyes stay on the circuit.

Everything below is part of Ohmie Pro, an auto-renewing subscription. Details are in OHMIE PRO SUBSCRIPTION at the end.

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
• Physics: charge, electric fields, Gauss's law, potential, capacitors, circuits, magnetism and induction
• 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

MOMENTUM THAT FORGIVES
XP, streaks, daily quests, 28 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.
