Arduino with saved sketch?

Question

Arduino

Can the sketch be loaded into memory and saved? That is, write down, for example, a program that displays numbers from 1 to a billion, then connect it to another computer and it will continue to execute the program?

Answer 1

Of course you can, arduino constantly executes the sketch, and will output regardless of whether a computer is connected and which one.

Answer 2

When connected via USB to a computer, the arduino is automatically reset, and this is not cured by cutting the soft-reset-enable jumper.
