Arduino Uno Basic Question

[Bengali]

Hi,

very basic question, how do I read code already programmed on the chip?

I worked on this about a year ago, gave my laptop away, cannot
locate any backup files so all code is gone.

I'm trying to figure out if I still had working code programmed into
one of the uno's. How do I verify the code is there?

Thanks

Out of luck acording to these guys:

But maybe acording to these guys:

Unfortunately, before you upload the code to a microprocessor like Arduino it is compiled from the human readable script to machine code. You can't normally extract the source code from the compiled machine code.
Having said that, the link above from DUG suggests there might be a way (but I reckon it will be painful)
