Interacting

Hi!

I am trying to make a simple arduino project: i have an 16x2 lcd and i would like to display something that is happening on the computer for example it would display a current music playing name...

I want to know where should I look and start...

Thanks a lot in advance!!!

There needs to be some application running on the PC that knows what is happening, and is communicating with the serial port that the Arduino is connected to.

Can you create such an application, to collect the data of interest?

I do not know how to create such an application... This is the only thing that bothers... I heard a lot about processing. I saw the concept of processing + arduino for ambilight... I wonder if i could use that concept but to get info from an app...

Where is this music coming from? You can only use Processing if you get processing to play the music or find a way for it to tap into where it is coming from.
