In slalom training in Moscow (that is, on small hills with a height of 50-55 meters and a slope length of 250-300 meters), we sometimes put DYI timing system. The gate at the start and photocell at the finish, and the clock. Communication between start and finish over the air (radio). It so happened that we call the timing system for ski as “omega”. So, our omega broke – the radio channel stop working. So the idea arose to assemble a new one based on the Arduino, i.e. can say that without a soldering iron. In a series of notes I plan to cover the progress of work.
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.
