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.

Hi
Nice work with alpine timing system. Its very interesting system and i think i try to do it. Can you help little, what is best transmitter/receiver, if i understund right you are tried many different options. And what you think, is it work with alge photocell and startgate?
Best regards
Mika, have a good day!
Regarding radio channel. I do not like the work with nrf24L01 but till now I do not see real alternatives in Ali Express. So if to begin project now I would follow the same way as described in notes.
Regarding combination with other startgate and photocell. If they provide simple “switch-on-switch-off” input then no problem to use. If not – I do not know how to use.
🙂
