Hi,
This is a newbie question. I am trying to write a program to read the arrows(up, down, left and right) and move a robot arm accordingly. I have done it with Java, but no idea how to do it in Arduino IDE. I have already Googled for it but no results. Any ideas how to do it ?
Thanks for your help.

It can't be done with the Arduino IDE. The Arduino iDE is for developing programs that run on the Arduino. The keyboard is not connected to the Arduino, so it can't read the key presses.
Processing can read the key presses, and send information to the serial port, that the Arduino can read.
If having a computer hooked up is a bad situation for your needs, you could just use four buttons and arrange them as up,down,left and right.
Then read the buttons as usual directly in the arduino.
Just thinking out of the box, hope that helps.
Thx for your help guys 
As said I have allready done it before with Java & Remote Control. Was just wondering if I could do it with Arduino IDE, but clearly there is no point
