Im guessing thats the latest. The sketch worked fine until I updated a few weeks back to 1.8.1. I even tried uploading other sketches, even a blank sketch.
The board is not a nano original but it works like one and I have used it for quite a while and others just like it, its from tinysine. Today trying to upload a modification to the sketch on the board ( changed analog pin A0 to A1), it would not upload, giving an avrdude out of sync error 1 thru 10.
I opened up an old 1.7.6 version of arduino IDE and it uploaded but it doesnt seem to run.
What can I do?
