Keyestudio Micro:bit Mini Smart Robot Car V2 - Light Sensing

Light Sensing
Description
The micro:bit robot shield comes with a photocell sensor element controlled by P1 interface.
Photo resistor (Photovaristor) is a resistor whose resistance varies with
different incident light strength.
In the project, we will use the photocell sensor to detect the ambient
light intensity, controlling the color brightness of 18 WS2812 LEDs on
the KEYES-2812-18R module.
The darker the ambient light, the brighter the 18 LEDs.
