If you just want to measure light using the built-in facility then you just need a micro:bit.
When it comes to the choice of resistor to use, I have used a 2.2kΩ resistor here, but a 1kΩ or 10kΩ resistor will also work, but will change the range of readings.

CdS cells are little light sensors. As the squiggly face is exposed to more light, the resistance goes down. When it's light, the resistance is about ~1KΩ, when dark it goes...
