aliraza786,

I think it's a better solution to send a command to your circuit using your web browser. Run a http server on your computer and connect to it using your web browser. Make a http form to capture the speed and send to a file, then that file will be able to be opened by matlab and send the value to your board. Another suggestion, use SSH to connect to your computer and build a program in C or in Python, or compile your matlab script, to configure your fan controller.

Hope I have been helpful.

the first line of this instructable shows that webserver can be used for controlling robots and home automation.

With that you have an apache server, you are able to store web pages in your computer. Build an web page with forms and record the information on a file. I think you can use javascript or Python for that. Good luck!

There are two toolboxes in matlab that may help you. The first one is TCP/UDP/IP Toolbox, which has all the necessary commands in order to send and receive data via internet and the second one is Instrument Control Toolbox, which is for connecting instruments (such as oscilloscopes, frequency generators etc) in matlab, but as stated in Mathworks' site: "For remote communication with other computers and devices from MATLAB, the toolbox provides built-in support for TCP/IP, UDP, I2C, and Bluetooth serial protocols".

I've used Simulink in the past in order to exchange data between two computers and I think it's the easiest way if you have some familiarity with Matlab. In Simulink you use state machines in order to run your code. The general idea is that when you run your program you will enter a state in which you will do all the necessary initializations and wait there. You will leave this state whenever you press a key and in the following states you will do all the data transactions with the other computer.
