Sebastian Lague

Sebastian Lague is a programmer who makes videos about creating things with code. His “Coding Adventure” series follows projects built from scratch, one step at a time.

Each video follows one project, such as a chess engine, a Rubik’s cube solver or a simulation of how computers store memory. He explains his thinking, shows what goes wrong and steadily improves the result. The visuals are clean and the narration is gentle and clear. Videos are long, but they move at a steady pace and suit beginners as well as experienced coders.

Some highlights include:

This video builds up how computers remember information, starting from simple logic gates.

This one explores how computers work by simulating the circuits inside them.

This video follows the process of programming a chess engine and improving it step by step.

The channel has around 1.4 million subscribers.

Sebastian Lague links software engineering with the electronics underneath it. His videos on computer memory and logic gates are a natural bridge between GCSE Computer Science and electronic engineering. His projects also show how game development, graphics and simulation rely on maths and careful problem solving. Watching a project grow from a blank screen shows how much patience and testing real software needs. The chess and Rubik’s cube projects are also a fun introduction to algorithms and search.
