Sketch is not being received by Arduino even though Arduino Editor acts like it is finished?
Thank you to all who have suggested corrective action for my posted communication problem. After trying all of the suggestions, I threw up my hands and deleted all evidence of Arduino Create Editor. Next I installed the Arduino Create Editor as a fresh/new install. Magically, all of my communication issues with the Arduino Uno have been corrected. Apparently, something in the communication code was corrupted during my first attempt install on my desktop PC.
