Wifi Shield Communicating with Arduino and PC

Using Arduino Interfacing w/ Software on the Computer
#1

As part of a school project i plan creating a remote controlled vehicle which does some general environment sensing. The issue im having is that i want to fully understand how to program the wifi part before i purchase any parts. There are two parts of this i don't currently understand, firstly, is the wifi shield able to communicate with the Arduino so ii can then control a motor driver and how would i go about sending the information to the wifi shield (directions etc.) over wifi so that the shield will tell the Arduino what to do.

Just for clarification: Arduino Mega2560 Rev3 Arduino Wifi Shield Arduino Motor Shield Rev3 (Just for context)

Thanks, :)

firstly, is the wifi shield able to communicate with the Arduino

Yes, but the communication is handled entirely by the Arduino.

how would i go about sending the information to the wifi shield (directions etc.) over wifi so that the shield will tell the Arduino what to do.

The shield doesn't tell the Arduino what to do. The Arduino asks the shield if any connections have been made, that might be defining what it needs to do.

The Arduino with WiFi shield needs to be a server, responding to GET requests.
