Hello,
in order to use arduino web editor to programe my arduino nano
i had to know the micro-contrôler used in it.
Please how can i reconize it, see the image in attachment (atmega 168, 328 or 328 old)?
Most are going to be 328 or 328 OLD.
Only you know what you have there as we cannot see it, and only one of them will properly UPLOAD.
The other tends to error out and wont actually upload.
There is a web editor specific section too so lets see if they will kindly move this there for you.
