Serial Port not existing!!

Hello guys!

i'm doing a project for my graduation which is a robotic hand controlled via LeapMotion controller. I'm using java script and Node.js to let the LeapMotion communicate Arduino via serial port and websocket modules, but the problem is that there's no serial ports existed in my laptop (Macbook pro). When i try to run the program on Node.js a message show up and say "Serialport Dependency". So guys if anyone can help me to solve this problem please do it because i've been searching on the internet for months and i can't find anything.


Physical serial ports don't exist on most modern computers anymore. The Arduino board's USB port will emulate a serial port, but the Arduino has to be plugged into your Mac for other programs to see it. This is the same port you would usually use to program your code into the Arduino.
