Hi, i am really new to Arduino and programming at all. I got a Pan-Tilt Unit-D46-70 ( http://www.flir.com/mcs/view/?id=53712 ). I can tilt and pan the device without any problem using the serial interface via rs232. Now i had the idea to create a little arduino sketch to use a Saintsmart LCD keypad …

How to use RS232 in that case?
