What guide thingy did you use? I have had my Uno for 4 months now and can't use it :0 =( Can you help me?
I've got an UNO R3 and I'm using windows 7
I've got everything installed correctly, it's that, when I try to open the Arduino Application from the file arduino-1.0, it says "Could not find the main class: processing.app.Base. Program will exit." I got all the drivers on correctly (manually loaded them from arduino-1.0, complex)
