Hello all, thank you in advance

I would like to make a device that has an lcd readout, and to which informtion can be sent regarding temperature and fan speeds. This would go into my computer. I have a decent amount of experience working with computers, but have no experience with programming or microcontrollers. i am, however, very eager to learn!! Any help is appreciated!

 

If you want to build the interface circuit on your own, you could refer to this page for an example http://www.beyondlogic.org/serial/serial3.htm. This circuit uses UART and RS232 port.

If you want to just buy ready made modules and connect them together, then something like this is appropriate http://www.seetron.com/slcds.htm

There are many example circuits published on the web for RS232 or parallel port controlled LCD display (text or graphic). Or ready made modules as well. You could google them to find one that suits your need.
