Hello everyone. I am brand new to Arduino so sorry if this is the wrong area to post this, please point me to the right area if so.
I am trying to replicate the remote trigger switch for my Panasonic GH1. The electrical schematic required is basically two switches that change the resistance seen by the camera. See the following website to see the schematic: http://www.robotroom.com/Macro-Photography-2.html
I want to use my Arduino UNO to remotely trigger the camera every few seconds to put together a time lapse video. Eventually this will hook up to a small rolling cart that will move slowly along taking pictures every 30s - 1min to produce a nice photographic video effect.
I can't figure out how to actually make arduino replicate pushing
a button. I can have it react
to a push button, but not push
the button. Do I need an opto-isolator for this? A relay would seem overkill.
Any help is appreciated.
