I have an arduino nano v.3 on a windowsill in the sun. Some afternoons, the IDE on the linux PC won't upload the program and reports "problem uploading to board" Next is random between "programmer is not responding" or a wrong response Throughout this, the nano continues doing its existing program for example blinking an LED, and is listed in
Repeating the upload from the IDE sometimes got a different "incorrect response" failure and sometimes worked normally. I have noticed that it has been more reliable in the morning and late evening. Is the uploader expected to be unreliable at elevated temperature? Do I need a cooling fan as well as the "sun hat" shade which improved things somewhat? Is there anything else which experienced users recommend?
