How to Make LEDs Flash to Music with an Arduino
Hello! Thank you for the tutorial first of all! I do how ever have a problem, I think it is a bit external to this tut but still.This line "arduino = new Arduino(this, Arduino.list(), 57600);" is highlighted and the error line tells me "error opening serial port /dev/cu/Bluetooth-modem: port busy. " although I didn't use the bluetooth to work in any way. Where should I look for to resolve this?
