I would like to know how to use USB Serial port to interact with an Arduino board to get data from it.

Many thanks in advance

The TI-84 doesn't exist. What calculator are you asking about?

If you are asking about the CircuitPython fork (not MicroPython) integrated on the TI-84+CE Python Editions, there is no way to do it from Python. You must use a native language such as C, C++, or ez80 to interact with the USB port.
Eh, it's not that bad, the calc's python can already talk to the TI Innovator or other boards like the micro:bit ones (see here)

So it might "just" be a question of calling the correct things the correct way (which may not be easy).
