I'm trying to control my Arduino Uno with Processing for the first time. I get an error on line "String portName = Serial.list();". I know that the Arduino is using Com3. The error is "ArrayIndexOutOfBoundsException:3". I assume I'm not entering this line correctly. The examples are by someone using an Apple, so maybe I'm typing the port number wrong.
