Can someone please help me? I have done everyhing like he said but yet when i go to processing and open beat write it said: Error opening serial port COM4: port busy. I tried changing: arduino = new Arduino(this, Arduino.list(), 57600); to: arduino = new Arduino(this, Arduino.list(), 57600);and this time it pulled up everything and didn't have any errors but when it opens up the beat write program it just goes to a white screen and doesn't respond. I need Help ASAP!
I've fixed all the problems except now it says: ==== JavaSound Minim Error ======== Don't know the ID3 code GRP1
