FpgaLearn vs Countries 195

A complete FPGA starter course in your pocket. FpgaLearn takes you from logic gates to state machines, bus protocols, timing constraints and board bring-up. Write code and see the waveform instantly; grading checks circuit behavior, not code style, and points to the first mismatch when something is wrong. START FREE • Stage 1, Digital Logic Basics: all 10 lessons free • Beginner exercises, the logic gate lab, the Verilog playground and a 303-entry concept wiki are always free • Unlock the full course with one purchase when you are ready THE FULL COURSE • 42 lessons in 4 stages: digital logic, Verilog, hands-on projects, then FPGA architecture, timing constraints, toolchains and HLS • 28 auto-graded Verilog exercises across combinational and sequential logic, FSMs, arithmetic and UART/SPI/I2C, at beginner, intermediate and advanced levels • 54 lesson quizzes with spaced review and a wrong-answer log WHY IT WORKS • Real four-state simulation (0/1/X/Z): a forgotten reset shows up as red X on the waveform • Behavioral grading: any correct implementation passes; failures jump to the first mismatch on the waveform • Tap-to-repair: practice the key logic without typing whole modules on a small screen • Learning map: prerequisites across 303 concepts and 42 lessons at a glance • Bookmarks and personal notes OFFLINE AND CLEAN Lessons, simulation and grading all run on device. No ads, no subscription, no account. PURCHASE Unlock Full Course is a one-time purchase, not a subscription, and supports Family Sharing. Restore it anytime from the Me tab.

Countries 195 makes learning the world feel like a game. Learn all 195 countries and build connections between the facts that matter: Japan → Tokyo → Japanese Yen → Japanese → JP → JPN → +81 → Asia → UTC+9 Explore flags, capitals, populations, currencies, languages, country codes, regions and world time — then reinforce what you know through quick quizzes, flashcards and challenges. LEARN THE WORLD Explore all 195 countries in one searchable collection. Search by country, capital, currency, language, code or time zone and quickly discover the information connected to each place. MASTER THE ESSENTIALS Learn and practise: • Countries and flags • Capital cities • Population • Currencies and currency codes • Languages • ISO country codes • International calling codes • Internet country domains • Continents and regions • UTC offsets and time zones PLAY TO REMEMBER Turn geography into quick challenges with: • Flag Sprint • Country Chain • Capital Match • Capital Rush • Which Country? • Population Challenge • Time Traveller Practise both directions — recognise a country from its flag, find a country from its capital, identify currencies, compare populations and calculate the time around the world. UNDERSTAND WORLD TIME Learn UTC offsets, common time-zone abbreviations, seasonal clock changes and the International Date Line. Time Traveller asks practical questions such as: “If it’s 09:00 in London, what time is it in Tokyo?” BUILD MASTERY Countries 195 tracks what you have seen, what needs more practice and what you have mastered across different skills. Your goal is simple: 195 countries. One world. Learn them all. No account required. Learn at your own pace and watch your mastery of the world grow.
