That's right, the iRobot Roomba is now supported by the EZ-B. No more wires! Bluetooth connectivity to your Roomba with the EZ-B. All you need is a PS2 connector (from an old mouse or purchase one new from an electronic supply store).
The EZ-SDK and ARC both support the Roomba commands. There is even a Tone module which allows you to write music on your Roomba
Get yourself a PS2 Mouse and cut the end off but leave a 12 inches of wire. Strip the wires back and use a multimeter to probe and find the ones that I connected in the picture. You only need to connect 2 wires, Signal and GND. Attach a servo plug to the end and connect it to the EZ-B.
In this picture, Signal is WHITE and Gnd is BLACK.
Also notice that this is the inside of the plug. That gives you a better idea of what pins you are connecting.
PS, the PS2 connector will have a little TAB in the center, break it off with a pair of plyers because it won't fit in the roomba.
*Note Before Connecting To EZ-B:: Check the signal wire (white wire) with a volt meter and ensure you have between zero and five volts from the Roomba. If you see higher voltage, you're connected to the wrong port. If you apply too much voltage to the the EZ-B from the Roomba, you will damage the D0 port and will require a chip replacement.
