As such a low-priced kit with all the important ingredients. But: The temperature sensor works only partly. I realize that this is a rather cheap part but +/- 7 ° C and the inertia of a medium-sized diesel must not exactly be. However, the manual is indeed in German without a man has seen it apparently taken directly from Google Translate. Some examples: "How should one logic like a volcano using [...] For example, you can make that watered your plants, if they are too dry [...] The variable is a number that you have given a name. . [...] The result of a complete CIRCUIT with correct code to review and upload. ". (I'm not a complete novice and know at least where is the soldering iron front and rear, so that was not so bad, especially as the comments in the sample programs, although in English, but are very good.) How to get to the sample programs, is described incorrectly for Linux - here sleuthing is needed. You also have to sign mandatory on the website. Why is this good (together with the name and e-mail address) but I do not see. But the biggest problem was the cheapest parts that jumper cables. Some of them are in fact defective! In itself not a big problem, sometimes short, by measuring and sorting. But it must also come only once - and by then some time has passed with troubleshooting. It took some head scratching at me until I'm draufgekommen, which is why some circuits behave rather strangely. Minor cause, major effect. Even if the cable itself are not critical, for a beginner can exactly be a frustrating experience.
