Is it possible to transfer text information from arduino to arduino, using ordinary pins, for example, 10,11,6,4,7, etc. instead of 1 and 2?

Question

Arduino

Is it possible to transfer text information from arduino to arduino, using ordinary pins, for example, 10,11,6,4,7, etc. instead of 1 and 2?
Perhaps I do not understand the problem correctly for myself.
I want to connect to one arduino at once, for example, three, and all this should be by wire. Accordingly, it seems that it doesn’t work through the series because this thing works through pins 1 and 2.
How to be?))
Thank you.

Answer 1

SoftwareSerial

Answer 2

It is more convenient to connect them via TWI or SPI.
