Good evening!
Now I'm developing a project that required the use of UART'a. I tried to figure out what this thing was, but I didn’t understand anything, because either I don’t know how to google, or I don’t understand realeo.
Please tell me where you can read about UART, namely how it works, how to connect to microcontrollers, what microcircuits are needed for this, etc.
Thanks in advance

Lots of articles.
Here is a Wikipedia article , there is a lot of information on working with the UART interface on ARM, AVR, MSP40 microcontrollers, and of course an article on Habré .
In general, in any technical description for a microcontroller there is a completely sane description of how it works.

If the controller has a UART, set the operating mode and baud rate for it. If RS-232 is needed, the corresponding controller legs are connected to a MAX232 type converter (connection diagram in the datasheet).
