I had the idea that it would be nice if I can get my Arduino to send out signals to my Sony (Video) camera via LANC to take a photo at set intervals - kind of like time-lapse.
I found http://www3.nbnet.nb.ca/dmeed/sony_lan.html which indicates that the LANC protocol is somewhat known (and a subset of it also works for Cannon cameras). But it can be a little tricky to get working. Unfortunately it doesn't seem to include a command to take a still image - only to start recording to tape, but I might be able to scan a remote signal control to find this.
I guess the other option is to send a digital output from Arduino to a relay which essentially presses (shorts) the appropriate button on the remote control. Simpler, but less flexible and also less robust as I have to rig the remote control to point at the camera.
So I thought I would see if anyone has tried LANC interfacing or got it working.
