I got a new Explorer board and followed the directions on getting started
Board selection and port selection in the Arduino IDE seems to work fine.
I can successfully request board information via the Arduino IDE.
However, when I try to send a simple program (e.g., Blink) it compiles OK but this just freezes saying
“uploading…” in the ide. Seems like a USB issue. I tried a different computer but had the same problem.
Any suggestions - I feel like I missing something fundamental regarding the use of the USB port.
Sorry for the newbie question.
