Now I have a small house connected to the world. Normally its a house to be illuminated by a tee light. Now it is equipped with an 8mm WS2812 LED. The LED is controlled by an Arduino (sketch), which is connected with a USB cable to a Raspberry Pi. On the Raspberry runs a little Python program, which gets in regular intervals the actual colour from cheerlights. The world can change the colour via a tweet, e.g. “#cheerlights green”.

The Raspi installation had no problems; Raspbian, Ethernet with DHCP, Wifi with fixed IP.
