# Python code to set LED colors of DB1 based on current weather in Boulder, CO.
# Hot weather (100F) will set the LEDs red. Cold weather (0F) will set the LEDs blue.
# Weather in between will set the color ranging from green to yellow.
# Weather API from: https://www.geeksforgeeks.org/python-find-current-weather-of-any-city-using-openweathermap-api/
