I am working on a project that can take a picture of a analog dial and read the numbers off of it.
I read that as saying the arduino takes in an image of an analogue meter, then does some image processing and returns a number based on where this needle of the meter is pointing.
As with anything to do with image processing the answer is no at the present.
However when the new Due comes on stream it might be possible to do it with that but it is no simple task.
