We'll be using CircuitPython as an alternative language for this project. Are you new to using CircuitPython? No worries, there is a full getting started guide here.
Adafruit suggests using the Mu editor to edit your code and have an interactive REPL in CircuitPython. You can learn about Mu and its installation in this tutorial.
When the code starts it turns off the Neopixels and puts up the shades. Then it continually checks the light level and turns on the Neopixels if it's dark enough, or puts down the shades if it's bright enough. If neither is the case, it turns off the lights and puts up the shades.
