Wire and code Arduino circuits in 3D
learn-arduino-red.vercel.appBeginner Arduino course built around an interactive 3D Arduino Uno, with 16 free lessons, from meeting the board and blinking an LED to motors, servos and a final project. 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.

Learn GCSE energy physics in a 3D book
iamtechartist.comInteractive 3D book on GCSE energy physics, with ten lessons on energy stores, power, efficiency, heating and conservation of energy. Each diagram lifts off the page as a 3D ink drawing, and energy flows as glowing colour between energy stores and transfers. Students predict, test and lift the flap for each answer. It also has an index, a quiz, a source for every number and a teachers' guide mapped to UK and Indian exam boards.

A treemap shows what is left, figures come from HM Treasury, and the builder vibe coded this government spending game.
