So i went to the Configuration Window of my laptop, choose Hardware & Sounds -> Device Manager. But i know, i forgot to installate the driver for the Arduino UNO. I searched on the Arduino site (and forum and Google) for errors and troubleshooting but i can't get it working. I looked in the menu at extra-> serial port. Then i get the error: Serial port 'COM3' can't be found.

But after that, i've changed the code in the Blink example (i would let blink 2 leds) and tried to upload it. I uploaded it and it seems it was successfull. I opened the Arduino.exe and i opened the Blink example. I plugged in the USB cable with my Arduino UNO board. I've downloaded the Arduino Software on the official website, and unzipped the folder. Yesterday i used my new Arduino UNO for the first time.
