  • @waala and @Toasty... I was having the exact same problem and I was able to fix it by doing two things.
    1: Close the Arduino IDE after uploading the code. I think the IDE may be locking up your serial port.
    If it's still not working...
    2: Change the arduino port in the Processing code. I had to change it from Serial.list()[0] to Serial.list()[1] to reference my COM4 port.

No public wish lists :(
