I am very new to Arduino devices.
I bought my first Arduino Uno device from Amazon(Link)
My operating system in Windows 10
I was trying to upload program from Examples>Basics>Blink
For every try I was getting following error:
Sketch uses 930 bytes (2%) of program storage space. Maximum is 32256 bytes. Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes. avrdude: ser_open(): can't set com-state for "\\.\COM4" An error occurred while uploading the sketch
I tried with USB 2.1, USB 3, USB C(with converter for usb C).
But same error. I tried reinstalling drivers, software but no luck
I thought my board has some issue, hence I replaced my board with new one.
But still same issue.
I checked all other forum posts but no luck.
