Serial to computer and IO expansion?

Using Arduino Interfacing w/ Software on the Computer
1

Hi,

Is it possible to have the Arduino UNO connected to the computer via USB serial interface and also have few digital IO expansions?

I'm trying to use it as a USB joystick with plenty of digital IO inputs for a flight sim interface, the ones on the UNO board isn't enough.

Thanks!

Yes no problem.
Shift registers are popular for more input / output.
