can't program arduino.

Hi, when I try to program my uno it gives me a error. P.S when I try to access com ports it is grayed out! thanks!

Hi caleb121341,

It is all about follow the rules. First check if you have the ide installed corect. Than check if the usb driver is installed this can be found in the folder drivers. If all looks ok. than mention in return the error code which you can found in the lower left corner.
