I'm new to Arduino, and wonder if it is possible to "read" the sketch that is in an Arduino Uno R3?
My first program worked fine until the Arduino and accessories were finally packaged, but now there appears to be some other program running in it.
Attempts to put my known, good sketch in the Uno don't change it. However, the "blink" sketch does load and run fine.
I'd like to see if the sketch in the R3 is the same as my "good" sketch. Is that possible?
Thanks!
John
