After Ron’s great assistance in December, I was able to to use the dome and rotation controls. Unfortunately, while updating my hand controller firm ware and doing a system restore, my computer crashed. The fine folks at Microsoft had me do a full Windows installation, which wiped all of my files and settings.
I am back up running now an I thought that the reinstallation of the dome controls would be a snap, as I am much more comfortable with the set-up.
Following the directions, I plugged in the USB connector and the connector. The computer did the proper installation of the Arduino device. That was a good start....
I then went to the Device Manager to record the proper comm port an as the next step in the instructions. There was nothing there.
