Trying to upload Blink example (Arduino sketch) on my Arduino uno Arduino: 1.8.3 (Mac OS X), Board: “Arduino/Genuino Uno” Sketch uses 948 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. Problem uploading to board….
