How to make a signal output to several pins at the same time?

Question

Arduino

Good day to all dear residents of the toaster! I saw this when programming the AVR. There you can output signals using a byte like 01110001 . How to do this on an arduino, you just need the signals to be given at the same time. Thanks in advance!

Answer 1

You can use the code from AVR( write to port ) because Arduino is just a library to manage all these commands.

Answer 2

For example, you can do as it is written in the instructions
