I was working with Arduino for school and I had to work with the Blink file in examples. When I plugged my board into my computer, a new comport doesn't appear and when I try to upload the file it doesn't do anything. Does anyone know what to do?
Did you forget to install the driver?
Which board? Original or clone?
Which operating system?
It probably did something; possibly telling you that there is an error. And what is it? IDE, Arduino, ... ?
