Costruire un laser trigger per la macchina fotografica con arduino

There are loads of reasons for why you could want to trigger your camera remotely – to avoid camera shake, for example, or to be able to take a photograph of yourself without having to rely on a timer. If you want to build more ambitious projects, however, you may have to consider getting more exotic. I recently built a little device which triggers my camera whenever a laser beam is broken – It’s about as simple an electronics project as you can pull off, but it’s going to form the base of a couple of other cool projects I’ll be working on going forward (stay tuned…), so I figured I’d do a quick post explaining how I did this.
