"port" is greyed out in 1.6.13, running win 10 for an Uno R3 I am new to this, and my kid got an Elegoo smart robot car kit v2.0 for Christmas. We assembled the car, but after downloading the software, the program always states:


  Arduino: 1.6.13 (Windows Store 1.6.13.0) (Windows 10), Board: "Arduino/Genuino Uno"
  
  Sketch uses 2,242 bytes (6%) of program storage space. Maximum is 32,256 bytes.
  
  Global variables use 210 bytes (10%) of dynamic memory, leaving 1,838 bytes for local variables. Maximum is 2,048 bytes.
  avrdude: ser_open(): can't open device "\.\COM1": The system cannot find the file specified.
  
  Problem uploading to board.  See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
  
  This report would have more information with
  "Show verbose output during compilation"
  option enabled in File -> Preferences.


I don't know what other information is important. Can somebody please help me?

Thank you.
When the port is greyed out its not available (I know you had worked that out) so you have a problem with you serial to USB drivers.

Looking at the kit I think you are connecting the UNO to a USB port on your PC/laptop using a blue cable.
 1. Please can you check that the cable is connected properly.
 2. Can you try a different USB port on the PC (don't use a USB hub - some don't work).
 3. Does Windows recognise a device has been plugged?
 4. Are you running it as administrator, you will need to be to install the drivers.
 5. Can you try connecting it to a different PC?

If these don't fix it then, please comment and well go through looking at the device manager.

Hope it works, it looks like fun.
