I'm brand new to arduino but I'm trying to figure out how to set up a WASD steering system for my robot I made.

I have the physical setup all ready but I don't know the code to use that would allow me to use my computers keyboard. I would like to still have my keyboard attached to my computer while I do this. I.E. I don't want to manually plug the keyboard into arduino.

I asked this on Robotics stack exchange but they said to ask here.

A list of functions/blocks Iof code that is applicable would be the best answer, but I'll take anything that'll get my bot moving :)

Edit I'm using a wireless keyboard, but my arduino is connected via USB.
