During the last MakerFaire Hannover, I found the very nice RGBDigits by Coen de Bruijn. I purchased the clock shield with 4 RGBDigits and a real time clock.

Finally I programmed some patterns for the NeoPixel rings.

Unfortunately the colours are not as bright as in real life.

The description of the patterns is below:

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”.

As an eye-catcher for future MakerFaires and other events I tried to create the logo of the Arduino Group Hannover in 3D. I have no 3D printer at home, and the printers I know are much too small.

Now – that I get a little comfortable with github – I will put some of my Arduino sketches onto my github account.

Last year a NeoPixel ring with 24 LEDs  blinked in our Christmas tree. I presented it on the last MakerFaire Hannover, but unfortunately it was too close to the Tesla coil on our booth, and it stopped working. To be prepared for this year’s Christmas I ordered new rings from Watterott – not one, but three: 16, 24, and 32 LEDs.

Again this year the MakerFaire Hannover took place, and the Arduino Group Hannover participated.

Today I got two new toys from my wife:

The Arduino Robot:

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.

Last weekend the MakerFaire Hannover 2014 took place, and the Arduino Group Hannover attended the Faire. Again Watterott was one of the exhibitors – it was clear, that this will be an expensive weekend ;-).

One of the things I bought was the NeoPixel Ring from Adafruit – a very nice toy!

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.

I’ve written a short article (in German) for the blog of the Arduino Group Hannover.
