Approximately 10 years ago, “Arduino” – platform for do-it-yourself of automation projects appeared.
I’m afraid to make a mistake, but about 20 years ago, microprocessors reached the level of “single-chip computer”, that is, in addition to the processor, the microchip has memory, the ability to load programs and of course keep input-output facilities. Nevertheless, until Arduino this area remained for specialists.
Arduino gives an opportunity to engage non-specialists in automation, that is, it is not necessary to be able to program at a low level, to use a programmer. And in general, you can not know “for what end to hold a soldering iron” 🙂 For all this, a single-board computer is provided. This computer is programmed via USB, using a “normal” computer on which the programming environment is installed. Various sensors and modules can be connected to the I/O of the board, and this can be programmatically linked using the “libraries” from the Internet.
In this section, for convenience, links to all notes on the topic: “DIY timing system for ski with Arduino” are collected.
