hello and welcome to my post XD.
i am wondering if any body reading this would know how to program a arduino so that when connected to my computer via a usb cable the keyboard input from my computer would tell it what to do.

for example presses the w key on keyboard and light on arduino turns on
releases key and the light turns of

thank you for any help given have a nice day.

There are some tutorials on the web (google "arduino tutorial"), for example http://www.ladyada.net/learn/arduino/

In general you can talk to an arduino through the USB port using the serial monitor, and the Serial class in your code. The link above will take you through that.
