I've been a massive idiot and accidentally deleted the sketch I need for a project at university, and I didn't create any backups. The sketch is already uploaded into the arduino, which operates using the serial monitor; when "1" is entered it does one thing, when "2" is entered it does another thing and so on. My question is: can I still use the serial monitor to operate the arduino without having the original sketch?

Any help would be appreciated, thank you.


Of course you can. The serial monitor has nothing to do with the sketch - it's just a very primitive serial interface program.

You don't even need the serial monitor. You can use any serial interface program ("terminal emulator") such as Teraterm, Putty, Hyperterminal, etc.
