Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.

Describe your idea, get ready-to-upload Arduino code
Describe what you want the board to do in ordinary sentences and the generator turns it into a structured Arduino sketch.
Works as a starting point for the Arduino Uno family and the many compatible clones and derivatives that share the same programming model.
No configuration or setup step; the site is built around generating code immediately after you state your goal.
Nothing to install and no account required, so it can be used from any machine, including a school or library computer.
