I have a question

I have no experiance with programming but want to make a security spot light which tracks a person within an environment.
Can this be done?
How do I go about it?

Thanks for the help.

It depends how "clean" the environment is, i.e how easy it is to separate (segment) a target from the background, and what constraints there are on the movement of the target.

Very difficult to do with an Arduino in most cases, I'd say.

Have a look at Roborealm for machine vision prototyping.

You should only post your question in one section. Not every section that applies.
