ARK vs Ohmie

ARK is the project-sharing platform for makers, engineers, students, and creators who want to build real things and help others do the same. The new ARK experience goes deeper into the create-project flow, making it easier to document your work with detailed instructions, structured steps, materials, files, and notes so other people can understand your process and give the project a crack themselves. The app now features a sleeker, cleaner UI built around discovering and sharing projects more easily. Projects can be tagged directly in Explore, with difficulty tags like Beginner, Intermediate, and Advanced, as well as category tags such as Robotics, AI, 3D Printing, Electronics, and more. Users can also headline their posts with intent-based tags like Help Needed, Shameless Promotion, Build Log, Showcase, or Question, making it easier for the community to know what kind of feedback, support, or attention a post is looking for. ARK is becoming more than a place to post what you made. It is a place to document how you made it, help others recreate it, and build a living library of real-world STEM projects.

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 • 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. OHMIE PRO SUBSCRIPTION Ohmie is free to download. The lessons, practice, circuit sims, Ohmie World, Ask Ohmie and everything else described above require an Ohmie Pro subscription, billed monthly or yearly. The yearly plan starts with a free trial for eligible new subscribers. Prices are shown in the app before you buy. Payment is charged to your Apple Account. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it any time in your Apple Account settings.
