MicroController Learning Lab vs learnFORTH

MicroController Learning Lab is the ultimate interactive learning tool for anyone who wants to understand microcontrollers — from complete beginners to experienced engineers looking to sharpen their skills. Whether you are exploring electronics for the first time or building your next embedded systems project, this app gives you everything you need in one place. What's Inside: Curriculum — Structured lessons covering microcontroller fundamentals, digital I/O, analog sensors, PWM, serial communication, interrupts, and more. Learn at your own pace with clear, focused explanations. Interactive Simulators — Five animated simulators let you visualize how circuits and signals behave in real time. Watch LED blink patterns, PWM duty cycles, ADC conversions, and serial data come to life on screen. Breadboard Lab — Wire up real project circuits on a virtual breadboard. Auto-Wire builds the connections instantly. Then launch the Live Simulation to see your circuit running with animated signals and pin states. Illustrated Diagrams — 30 hand-crafted technical illustrations cover everything from pinout diagrams and circuit schematics to communication protocol timing charts. Real-World Projects — Eight guided projects show how microcontrollers are used in actual applications: soil moisture monitors, weather stations, smart relays, motor controllers, and more. Reference Library — Quick-access tables for GPIO pinouts, register maps, timing values, and common code patterns — everything you need without leaving the app. Microcontrollers Covered: ATmega328P (Arduino Uno), ATtiny85, ESP32, RP2040 (Raspberry Pi Pico), STM32 Who Is This App For: Students in electronics, computer engineering, and robotics courses. Hobbyists building their first embedded project. Engineers who want a fast visual reference on the go. No prior electronics experience required. Start from the basics and build up to real working projects.

It's time to learn Forth, the compact stack-based language that powered navigation computers, embedded systems, and a generation of hands-on hackers - and still runs the boot firmware on some retro Sun and Apple hardware. If you ever saw a Jupiter ACE home computer, now is your change to learn about what made it special. This app teaches you to think in words and stacks with 90 short, structured daily lessons, a live REPL you can experiment in right on your phone or iPad, and hands-on exercises with hints (not answers) so you actually learn the ideas. WHAT'S INSIDE • 90 guided lessons across 7 topics: the data stack, words & variables, control flow, loops & recursion, advanced words, data structures, and advanced topics. • A built-in REPL with syntax highlighting so you can type real FORTH and see the stack respond immediately. • Exercises for every lesson, graded on output, with an optional hint if you get stuck. • Daily streaks and per-category progress tracking to keep you moving. You'll learn, promise! • A plain-English primer on Reverse Polish Notation and stack manipulation (DUP, DROP, SWAP, OVER, ROT) for complete beginners. • Historical notes on FORTH's dialects - fig-FORTH, Forth-79, Forth-83, ANS Forth - and which one this app's interpreter follows. • A tip-of-the-hat to the Jupiter ACE, the British home computer from the 1980s that was based on Forth. • A recommended reading list of classic FORTH books, including Starting FORTH and Thinking Forth by Leo Brodie. • Light, dark, and automatic themes. No prior programming experience required. If you've ever wondered how a language with almost no syntax can still get real work done, learnFORTH will show you, one word at a time. Note: This app is free, with all features always available. If you enjoy it, please use the tip feature to thank the author and encourage future development.
