Want to interface a PlayStation 2 Controller with an Arduino Microcontroller? You have come to the right place. Below you will find a link to download an easy to use library that takes care of all the interfacing for you, so you can start using the controller right away for your project. Don’t forget to link your cool projects in the comments, I’d love to see what you do with the library.

Outdated. Go to new library HERE
A while ago, I spent countless days trying to interface an Arduino and a Play Station 2 controller. I wanted to build a controller for my SAGAR robot, and figured PS2 + Arduino would be perfect. However, no matter what I did, no existing library would work for me. I shelfed the project for a while, but recently found this forum post with some code by a member named Shutter. I tried out the code, and to my surprise, IT WORKED!!! Well, mostly anyway. It didn’t really have analog stick support, nor was it formatted into an easy to use library.
1 Comment // Read more..A person has already come to me asking how to interface an Axon Microcontroller to LabView. Instead of a bland answer to the effect of “It’s nothing special”, I decided to write a quick write-up about communications between computer systems; and I will use the communication between my SAGAR robot and LabView operator panel as an example.
Read more..My SAGAR project has gotten to a point where I would like to document the system design through a series of detailed posts.
First I’ll show the new interface, and talk about how it communicates with SAGAR.

The video below is a screen capture of the interface as SAGAR runs a mission taking it around a parking lot. All communications are in the form of NMEA sentences. The DIYdrones ground station gave us a few ideas of what we wanted to do.

I used a Ardupilot program to generate the mission file with waypoints, convert it to a hex file using gcc, and I manually flash that into the Axon’s EEPROM memory. When SAGAR comes online, I give it a command to scan the mission file in memory, then I command it to run the mission.
Read more..I have been asked by a few people how SAGAR is going, so I guess I need to do some updates more often. Anyway, SAGAR was shelved for a while. The last tests of the closed loop heading controller showed I had something messing with the compass readings. Further tests concluded that my batteries were biasing my compass.
Read more..While waiting for parts to come in for SAGAR, I decided I’d kill three birds with one stone. I wanted to adapt my Irobot command code to be compatible with Webbot’s Lib, I wanted to test Webbot’s new Project designer, and I wanted to try out a Force Field Obstacle Avoidance Algorithm. This is what I came up with.
It’s an Irobot Create, controlled by an Axon 2 running Webbot’s Lib, a Sharp IR and a standard servo. Theoretically, obstacles in front of the robot will ‘repel’ it while free space ‘attracts’ it. The closer and more directly in the way an obstacle is, the more it ‘repels’ it away.

All right folks. The attached is my first attempt at writing a tutorial, so go easy. It goes over how I turned Li-Ion packs from obsolete equipment into usable packs for my SAGAR robot. For about $10 per pack, I built my own 14.4V 2.2Ah Li-ion pack, and in the attached pdf, I show you how I did it, so you can do it too.

For those who are unfamiliar with fish tanks, about once a week you have to change out roughly 10% of the water. The way we have been doing water changes involved two trips to the toilet with a mob bucket, and a lot of mixing of water in the shower. I decided to build a better way.
