A hardware kit and browser-based IDE that lets you write, run, and debug code on a real microcontroller.
No downloads, no drivers, no headaches. Get your kit, open your browser, and start creating.
Powered by Monaco — the same engine as VS Code — with syntax highlighting, autocomplete, and error markers built for your kit's API.
Try it in a lesson →Pause, step, and inspect every variable as it changes — so learners understand what the computer is actually doing.
See it in action →A live diagram of your controller updates in real time — every pin state, every voltage level, exactly when it changes.
Start a lesson →Your kit ships ready to go. Connect the USB cable and your browser recognizes it instantly.
Browse guided projects — from blinking an LED to reading a button to building your first game.
Browse lessons →Type in the Monaco editor, hit Run, and watch your code execute live on the actual device.
Step through your code, watch variables change, and see the board respond. No mystery.
Each lesson is self-contained, guided, and runs live on your hardware.
Real projects, real concepts. Every lesson builds on the last.
Your first program. Write a loop, control a pin, make something happen in the real world.
Open lesson →Read a digital input, track state in a variable, and display a count. Learn conditionals and signal processing.
Open lesson →Sequence 3 outputs with precise timing. Introduces state machines and structured thinking.
Open lesson →Measure time between events, store the best time, and compete against your friends.
Open lesson →Open the lesson browser, pick your first project, and write your first line of hardware code in the next five minutes.
