Good morning,
My Arduino Uno will not connect to the computer through port COM3. It keeps saying access is denied. I have reset the board, re-installed the software, rebooted the Arduino and the computer. The lights are on for the green power and the yellow flashing light when I plug in the USB. I am trying to load blink and it will not work. Any help would be greatly appreciated. I use windows 10.
Thanks Mark
