Hello all, I am new to the arduino and just purchased an Uno to mess around with. I am having problems getting sketches to load. I am running Vista on my laptop, have ensured the drivers are loaded and it tells me that the most current driver is being used.
My problem: the on light is lit and 'L' LED blinks constantly. When trying to load the blink example, all I get is an error that reads "serial port 'COM 4' already in use. Try quitting any programs that may be using it. Can anyone give me some ideas of what it could be?
