The firmware works with the Moodlight Pimoroni Kit.

Its main application is tracking sunrise and sunset times and adjusting the light color and intensity accordingly.

How it works:

• Given a location (which can be setup via the web GUI), the light will change color and intensity according to the time of the day.
• 30 mins before sunset, it will start shifting the color to a warmer tone (red).
• After sunset, it will gradually shift to blue for another 30 minutes.
• After that, it will turn off.
• 30 mins before sunrise, it will start shifting the color to a cool tone (blue).
• After sunrise, it will gradually shift to yellow for another 30 minutes.
• After that, it will turn off.

The GUI is a web interface that allows the user to set the location. With that information, it will display sunrise/sunset times, lunar phases, and other information about the astronomical events of the day.
