How To Use a Light Sensor with a Raspberry Pi Pico or Pico 2
In this tutorial, I'll teach you how you can use an ambient light sensor with a Raspberry Pi Pico 2 microcontroller and MicroPython. This simple project will get the current light level and then turn on the Pico 2's onboard LED when the light is low.
This project will also work on the original Pico.
You can expand on this to do some home automation actions, such as activate an automation on Home Assistant to turn on or off a smart light or smart power socket for example.
I'll be using VS Code as my code editor but you can follow along if you use Thonny instead.
