Learning apps built with Claude

Learn Arduino

Beginner Arduino course built around an interactive 3D Arduino Uno, with 11 free lessons from blinking an LED to driving motors and servos. Each lesson labels the board's pins and parts and pairs them with example code, a run button and a serial monitor, while the 3D view can be panned, rotated and zoomed. The builder says it was made with Opus 5.5.

Terra Africana

Browser 3D survey of five African monuments, from Great Zimbabwe and Bete Giyorgis to the Aksum stelae, the Great Mosque of Djenné and Meroë. Each site has a fact card with place, build date, material and UNESCO status, numbered notes on features such as the outer wall, and contour, masonry and line views with orbit controls. The builder calls it a quick exploration with Opus 5.5.

Mars Surface

Explorable Mars surface in a single 102 KB HTML file that starts inside a huge crater, with a six-wheel rover to drive over rocks and dunes. Players fly with WASD and press G to drop the rover in; it runs on WebGPU in Chrome with no game engine and renders a dusty scattering sky, a layered mountain and cracked bedrock. Built with Claude Code and Opus 5.5, with source on GitHub.

Moon Surface

Explorable moon in a single 72 KB HTML file: start inside a 48 km crater with Earth over the rim, walk with WASD and press G for lunar gravity. WebGPU in Chrome, no game engine, with craters down to centimetres and soft shadows. Built with Claude Code and Opus 5.5.

Petronas Towers Diorama

Live 3D diorama of Kuala Lumpur's Petronas Twin Towers, with buildings from real map data and noon-to-night lighting. It has traffic, people and lake fountains, and a crane that replays construction from the 1993 dig to the skybridge. Built with Opus 5.5 in Claude Code.
