I tried to upload the "fade" sketch and received the message below. What do I do next?
vrdude: ser_open(): can't open device "COM1": No such file or directory ioctl("TIOCMGET"): Inappropriate ioctl for device Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
I'm new at this and not very knowledgeable.
