so i got an arduino today, and i've been trying to mess around with it
after eventually getting it to connect to my laptop, i then tried to find and install the arduino.inf file, apart from the fact i cant find it anywhere in my files - i've tried to use my arduino without doing that, but it keeps on saying
'avrdude: ser_open(): can't open device "\.\COM3": The system cannot find the file specified.
Failed uploading: uploading error: exit status 1'
WHAT Arduino did you get? Is it genuine or a clone? What OS do you have(I assume windows with the COM3)?
Arduino.inf is in the drivers folder in the Arduino folder.
