My Arduino sketches will not upload no matter what I try. I'm running windows 10 and have the latest Arduino update, heres the error code:
Sketch uses 1,144 bytes (3%) of program storage space. Maximum is 32,256 bytes.
Global variables use 15 bytes (0%) of dynamic memory, leaving 2,033 bytes for local variables. Maximum is 2,048 bytes.
