Hello,New to this forum and a novice with electronics, so pardon me if this is a really silly question. As one of my early projects, I want to use an Arduino Uno to trigger the shutter of my Canon camera. Canon professional cameras, as you may know, use a shutter release cable comprising three leads: two hot ones for focus and the actual shutter release with the third being for ground. I'm only concerned with the one for shutter release. Short it to ground and the camera fires. So, how to do this with the Arduino? I've seen others use optoisolators to keep the camera's shutter release circuity completely independent of system current. Can I use a simple transistor instead? Is there a real risk of connecting the camera's shutter release circuity to the common ground?Apologies if I haven't explained this correctly.-David
