The Micro:bit actually has no light sensor, so how does it achieve this function?
Principle: "Micro:bit's LED dot matrix is also used to sense the surrounding light by repeatedly converting some LED drivers into inputs and sampling the voltage decay time, which is roughly proportional to the level of ambient light."
It's okay for programming enthusiasts who are just starting out to read, then learn from the simple time.
