Yes, but not one that supports that mode :-(

That is a good option to look at. Anyone done that?

I want to experiment to see if it can be reliably used to monitor some
instrument dials and blinking lights. A £10 webcam is a LOT cheaper than

via my Arduino board!

I also want to experiment using it /as/ an instrument as a water level
