Lesson titles are referenced so you can follow along. Lesson by lesson ## Every lesson in the kit’s order Lesson numbers and titles follow the "Super Learning Kit for UNO R3" tutorial (LA010), revised March 2024, with the sketches in its download. Each circuit uses the kit’s parts on the pins the lesson uses. 27 of the 27 lessons with a circuit run here, 1 setup lesson needs no circuit. 0 ### Installing IDE No circuit Setting up the Arduino IDE.

The page follows the kit’s lessons so you can use the two side by side; the circuits, sketches and explanations are Mokxi’s own. Do I need the kit? No. Every lesson that runs here runs in the browser, so you can try them before you buy a kit, or keep going while a part is missing or broken. Is the code the same as in my manual? The pins and the parts are the same, and the sketches use the same libraries where the kit does. The code itself is written for this page, with comments that explain each step, so it will not match the manual line for line. What do "with a change" and "coming soon" mean? A lesson marked "with a change" runs, but something differs from the kit, and the note under it says exactly what. "Coming soon" means we cannot simulate that lesson yet, and the note says why. We do not mark a lesson as running unless it does. Is it free? Yes. Every lesson on this page opens with no account. A free account saves your own copies of the circuits.
