Hi,
I tried to upload "fade" to the board and the following error occurred.
avrdude: Version 6.3-20171130
Using port:COM3
Using Programmer:arduino
Overriding Baud Rate:115200
avrdude: ser_open(): cant set com-state for "\.\COM3"
I am using 1.8.9(Windows Store 1.8.21.0)
the problem occurs on 2 different boards using 2 different cables
could someone please help me fix this?
Hi,
I'd remove that Windows Store version and download 1.8.9 from this site.
Software > downloads, scroll down to 'previous versions of current release' and click the link.
You may also need to search the site for 'cleaning up previous IDE' to make sure you fully remove the existing programs, folders, etc.

Thanks Peter and Bob, will do. Interestingly, when I turned the computer on this morning it worked fine.
Hi,
don't you love PCs...always something 'different' happening!
