# This script will get the current weather forecast from #
# Dark Sky and display a variety of stats on Pimoroni's #
# Display-o-Tron 3000, including temperature, humidity, #
# chance of rain and the UV index. The backlight colour will #
# change depending on the UV index and the bar graph will #
# increase as the chance of rain does. You can also exit the #
# script by pressing the joystick button too! #
