Ohmie: Learn Electronics

Ohmie: Learn Electronics makes electronics approachable through short, game-like lessons designed for active practice—not passive reading. Spend about three minutes a day solving interactive challenges, building schematics, decoding resistor color bands, troubleshooting circuits, and exploring live simulations.

Follow a structured learning path from charge, current, voltage, and Ohm’s law to op-amps, transistors, digital logic, embedded systems, and robotics. Practice GPIO, PWM, ADC, interrupts, serial protocols, sensors, motors, and PID control while building toward projects such as a line-following robot. XP, daily quests, and forgiving streaks help maintain momentum, while missed questions return in Practice until mastered. Ohmie contains no ads, and your progress stays on your device.
