Reading a sketch on Arduino Board


Is it possible to read a sketch that has been uploaded to an Arduino?
I don't see anything in the Arduino IDE to read from the Board the sketch is on?

Any ideas?


No, and yes.
You can not read the sketch, but with a programmer and the program 'avrdude' it is possible to dump the binary contents of the microcontroller. That binary contents can perhaps be disassembled into assembly code.
In most cases, writing a new sketch from scratch is less work.
