"Error compiling for board Arduino Uno

Velleman IO Boards
1

Hi. I am a newbie using my first Arduino compatible board. It is a VMA100.
I have downloaded the IDE 1.8.5.
I am trying out the “Blink” sketch and it is not compiling.

What is going on?

Thanks in advance.

Do you get any error messages when you try compiling? If so what does it say?

Hi Mitch. Thank you for asking.

Here is the message I am getting:

Open Windows Device manager and check to see what COM port your Arduino is assigned. Then you will have to choose the correct COM port in the Arduino environment. Hope this helps!
