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.

Ohmie's workbench has been busy:
- NEW Weekly Leaderboard — see where your XP lands against everyone else
learning this week. Tap the trophy at the top of any tab to check your rank,
and watch it move after a lesson.
- NEW Build your first PCB — an eight-mission guided project in OhmieCAD.
You design a real light badge end to end: schematic, part placement, routing,
design-rule checks, then spin the finished board in 3D.
Plus a smoother first run for new learners, and fixes throughout.
And as always: Ohmie keeps electrocuting bugs that could affect your experience.
