I just paid $30 for my ardiuno uno r3 and I am on win 7 and I have been dealing with the garbage for 5 hours. Please post a solution. I am trying to load the driver on this but nothing is working. I looked at the device manager and there it says "Arduino Uno" under other devices and there is an exclamation mark next to it. I can select serial port COM7 and selected the board uno but I cant load code onto it. It keeps giving me sync errors.


I even followed some guides on this website. Nothing.

I bought this at Creatron Inc., Toronto.
