Watching the weather nationwide at a glance, see temperatures rise and fall, watch the rain fall, all from a wireless, wall mounted installation.

A node.js script talks to the weather underground API and asks for the temperature and precip status of the 100 latitude/longitude points mapped to the LEDs and sends the spark core a list. The spark then changes the led colors based on the list it receives.

  • 1 × Spark Core
  • 100 × WS2801 addressable RGB LEDs
  • 1 × 1000uF cap Buffering LED power in
  • 1 × 300-500 ohm resistor on LED data in
