Thread Subject: arduino target matlab lcd display

Hello everyone,
I have a project in which i have to take the temperature of a sensor via arduino and make a fan spin accordingly.
Even though i am new to the electronics i managed to do that.
Now the final step is to display it in a lcd screen(display the temperature and the revolutions of the fan per minute,or at least one of these two).

Can someone help me please?
I have an arduino uno board and a 2x16 lcd screens which has 4 bits for input.

Arduino has a library(liquid screen) and i managed to use the screen.
But how can i do it in Matlab Matlab-Simulink?

Thanks in advance.
