For the first steps with the microcontroller technology I bought this set and am really excited. The variety of accessories allows a good introduction to the technology and a rapid build-up of the tests. When unpacking it was a bit like Christmas. In the past I've done a lot with electronics, therefore my circuitry is not alien. For the electronics amateur entry is certainly not quite so simple. What's pluses and minuses, you should already know. But among the many examples you get the basics in order to devise their own setups. The Arduino Uno I arrive quickly to the memory limits of 38 array elements was closing, now I have a Megaboard what thus has no problems. All in all a good compilation and highly recommended.
