Quite awhile ago I wrote a program for my UNO and it is working well. The problem is that I cannot find the original program to load it into another Arduino, such as a Pro Mini. Is there any way to safely read and copy the loaded program from the UNO to a file in my PC? If I could just read the l…

The code in the UNO is compiled code not C++.

It is possible to read the compiled code off the UNO and program a pro mini with that code, since both boards use the same atmega328 and are nearly functionally equivalent. The pro mini would need to be set up to run at 16MHz for any timing to work properly.

David, thanks for the response, but I need details on exactly how to do this, or I will probably screw it up badly. I'm kind of a novice, so be gentle (LOL).

It has been over a year since I did any experimenting with reading the flash memory off an arduino, maybe someone with more experience can post instructions on the process. Get two boards with the atmega328 processor (UNO, Nano, Mini, Pro Mini, etc) and practice with those before attempting anythin…

Thanks again David. I will try experimenting. The whole bootloader thing is foreign to be, but I imagine with a little google searching I can figure it out.

Fantastic!!! Thanks so very much for your time and effort, greatly appreciated. I will try it out later tonight.
