Arduino is a breakthrough technology in the amateur electronics ecosystem. Breakthrough does not mean that it introduces a new powerful microprocessor or something similar. It created an entire industry, a movement, nothing.I'm talking about the maker movement. Before the birth of Arduino, electronic products were not as interesting and easy to learn as they are today, and there are not many resources around. I studied electronics for many years at my technical high school and then at the Polytechnic Institute of Milan, but this is very serious, theoretical stuff, and there is very little programmingfun.
