To get the whole thing running, i decided to code in JSON [http://en.wikipedia.org/wiki/JSON] a question catalogue, with 2 different possible answers (Yes/No). To make it not too easy to answer, neither "yes" nor "no" is always the "right" answer. This was done by setting so called "categories" in JSON on the questions, meaning that half of the questions had to be answered "yes" and the other half with "no", just to avoid being punished. | To get the whole thing running, i decided to code in JSON [http://en.wikipedia.org/wiki/JSON] a question catalogue, with 2 different possible answers (Yes/No).

If the "wrong" answer was chosen, a signal was going to the stroboscope to flash the participant. But this was a much longer way than I expected. Not only was it my first time to ever program something in JSON, also the way to connect a computer with a "chip-free" machine like a stroboscope was much more difficult than I expected. The first misery was the fact that my chosen way of hooking up both devices via DMX and a DMX/USB Interface by Enttec [http://www.enttec.com/index.php?main_menu=Products&pn=70304] was quickly interrupted by the fact that DMX has two different Pin Standards (3 vs. 5) making it impossible to plug it in the relays I borrowed for my machine.. [http://www.uni-weimar.de/medien/wiki/File:2013-07-10_23.54.11.jpg] Fortunately the StuKo was able to help me out with an adapter, but it still didn't worked.. Even after trying a bunch of original software and driver packages by the producer Enttec and troubleshooting with the help of the internet and its vast collection of forums, it was impossible to get the USB port speaking with the relays to fire the stroboscope. | If the "wrong" answer was chosen, a signal was going to the stroboscope to flash the participant.

To get things running, I followed a hint and tried to hook everything up via Arduino device [http://www.uni-weimar.de/medien/wiki/images/2013-07-11_00.28.21.jpg] , which I fortunately knew from former courses. The advantages were simple but direct, the communication via the USB port was error-free and through the electric nodes on the Arduino Device it was easy to directly switch a relays, which directly switched on the stroboscope [http://www.uni-weimar.de/medien/wiki/images/2013-07-11_02.55.15.jpg]. | To get things running, I followed a hint and tried to hook everything up via Arduino device [http://www.uni-weimar.de/medien/wiki/images/2013-07-11_00.28.21.jpg] , which I fortunately knew from former courses.

After setting up my installation in the presentation room, I noticed that a lot of participants had fun with the fact that the questions got read out loud by the computer voice "Anna", and say "Gut!" oder "Böse!" was apparently, unintentionally funny! | After setting up my installation in the presentation room, I noticed that a lot of participants had fun with the fact that the questions got read out loud by the computer voice "Anna", and say "Gut!" oder "Böse!" was apparently, unintentionally funny! | ||
However, the feedback I received from people who answered all questions was rather good, although many people liked to be "bad" with intention or tried to fool the system and answer everything correct, just by thinking which the "right" answer could be. But in this last case, i'm happy and actually successful, because it motivated people to reflect their choices in everyday situations! | However, the feedback I received from people who answered all questions was rather good, although many people liked to be "bad" with intention or tried to fool the system and answer everything correct, just by thinking which the "right" answer could be.
