Cheerlights red

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”.

Arduino Yún

The setup of the Robot was quite easy, especially with the introduction videos of Xun and David on youtube.

For the Yún it seems, that I have still a lot to read.

In this article I will extract some of the documentation in the original neopixel library, so that I (and perhaps you) have it in one place without the disturbance of the actual code.
