I'm an Arduino novice. Started with a UNO R3 months ago and had lots of help here. Other things intervened and so just getting back into it and having to relearn some basics.
I have half a dozen ATM328 chips onto which I uploaded various sketches during that initial period. Some were moved to run independently on a breadboard. My note-making wasn't as thorough as I intend it to be in future, so I'm unsure what sketches are on what chips. Apart from recognising the sketch when run (like my trivial edit of the default 'Blink'), is there some way to discover the loaded sketch please?
