Interfacing with the computer

Is there any way that i can store the values form the serial monitor of my arduino into any file on my computer.

Need to use it for plotting a graph.

Total noob so please help fast.

Yes. Any programming language that has serial read/write will enable you to read and store the data over the serial line.

Try Processing.

Or you can use one of the free Serial terminal programs that save incoming data to a file. I use RealTerm : but there many others to choose from.

Or you can use GoBetwino and send data directly from Arduino into Excel, or log data to a file.
