What did you have connected to your EZ-B before it stopped working? And as DJ asked, what power source was you using?

The wire that is for the EZB which was not connected to nothing. The bioloid has its own controller which is no EZB do it would be use by itself.

The camera from DJ's head...

@Jerseylance For a teacher (and no offence but) you are kind of cryptic and not very forthcoming with information... What courses do you teach?

Art...

So The only thing you have ever connected to your EZ-B is the camera a JD head, and nothing else? And you still haven't answered the question on what power source you are using to power the EZ-B?

Is it a battery? What type is it, (LiPo, Nimh, ect)? What voltage is it? Are you using a power adapter? What type of adapter?

These are quite an important questions for you to answer to help us help you. You say that you are a future robotics student in another thread. If this is the case, then you need to learn to offer much more information and details when trying to troubleshoot problems and answering questions, otherwise you will struggle to learn what you need. Like @Richard said, you are not very forth coming with information which is making it hard to help you.
