Hi!! I was very excited to buy an Arduino R3 board on Sparkfun (I also bought a cellular shield SM5100). They arrived yesterday!! I followed the arduino website instructions: I downloaded the IDE software; when I plugue the arduino board on my pc (windowns vista), the green led turns on and the ambar led blinks. Untill here, it is all right but it does not work. The arduino uno port instalation returned an error “code 10”. I tried to reinstall the driver but the same error occurs. When I open IDE software, in “tool”, the option “serial port” is unable to click.
I chaged to other computer (also windows vista), changed the usb cable, I disabled my antivirus (norton), I followed the instructions of http://forums.adafruit.com/viewtopic.php?f=21&t=19931 and it does not work.
I need help, please!! Thanks!!!
