Java dilini kullanarak Android ve Web ortamında projeler yapabilirim. Ancak bir yazılımın bir donanımla nasıl iletişim kuracağını anlayamıyorum.

Thank you for the translate.;)

I can do projects in Android and Web environment using Java language. But I cannot understand how a software will communicate with a hardware.

? why 485 ? cable length ? multiple terminals https://www.maximintegrated.com/en/design/technical-documents/app-notes/3/3884.html
there are likely USB or RS-323 to RS-485 converters - but to write an OS driver for such (without the prior experience) is likely a head ache
