If you use raspian for the Raspberry Pi, there's ready-made software you can use.
Here are some links:

Yes this can be done. Here's a good link from Google, which includes an Arduino library link: http://store.curiousinventor.com/guides/PS2/

so in order to configure it would i use a specific os or could this be done with some programming

Electronics / Wired PS2 Controller for wheeled robot
« Last post by koolraj09 on April 05, 2014, 12:25:39 PM »
Hi all,
I bought a wired PS2 controller and I wanted to use it to control my 4 wheel, differential drive robot. Is there any way that i could do it, without using a micro-controller? Using a motor driver of some sort..etc? What other things I may need?

Actually i need the switches/buttons of the controller only...the simplicity and handling of PS2 for controlling a robot is what I need....
Thanks!

Thank you again. I read through some ROS tutorials, and it seems i can get through it.

It looks pretty good with complete documentation.
How is the warranty?
How is the customer service?

If you can run the mail server yourself, and have that forward to your mail ISP, then you might be able to do this from an Arduino WiFi shield. The reason it's unlikely you could send the alarm directly from the WiFi shield to your ISP is because modern mail sending protocols require a lot of processing power (often using TLS/SSL, check-before-send authentication, etc.)
A Raspberry Pi should have no problem doing that, assuming you configure it right.

You connect a RPi to Arduino using USB, just like to any other PC/computer.
The 256 MB version of the RPi only has one USB port. If you want to use USB to connect both an Arduino and a Webcam, that won't work (without a separate hub, which increases price and weight.)
If you go with the Raspberry Pi specific camera, rather than a USB webcam, then you can use the remaining USB port for talking to the Arduino.
If you want to get started with Raspberry Pi programming, there's a good forum over on raspberrypi.org. They're quite friendly to newbies.
Also, there exists a distribution of ROS for Raspberry Pi. This will require more learning up-front to get going, but will also then give you a lot of pre-built functionality, like vision tracking, navigation control, etc. You'd probably need the 512MB version to run ROS.

hey guys,I am working on an ISU I am wondering if i could use the arduino wifi shield to send emails

basically i am building a simple alarm system which when triggered sends an email to myself and alert me when i get the email on my phone

if not, the raspberry pi would be the next step(do i need to learn python and make a program)
  or could it be done with this module :

any other recommendations or ideas are welcome, thanks
