Ok ladies and gent i have a really dumb question being fairly new the Arduino area.
I had wrote a sketch it is about 30 lines approx, the laptop i wrote it on the hard drive went CRASH and stupid me i didnt do a backup.
So i know one option is to rewrite the sketch
But i heard someone talk of a way where you can retrieve the code from one Arduino and then upload it to another. How is this accomplished?
Thanks for any and all information.
