I am interested in starting a project in which I control the shutter of a camera with a photoresistor. I have been researching how to do so, but am unsure about which would be the best method.
I want to place an object on top of a photo resistor, and when the object is lifted and light is exposed to the resistor, the shutter fires. The most logical way of doing this seems to be hacking a remote for my Nikon D80 to the circuit and having this control the shutter. So far, I have found information about how to create a trip wire with a photo resistor and laser pointer, but not with only the photo resistor.
Any ideas or advice for me? I'm new to Arduino and need help!
