Arduino for time lapse photography

[RampantAndroid]

Hi all,

I'm looking to do some time lapse photography, but on the cheap, and DIY using a Arduino board. I could do a infrared emitter to trigger photos, but that has line of sight to keep in mind. I'd rather use a cable.

So does anyone know if it's possible to mimic a MC-DC2 cable using using an arduino? Do we know the functionality of each pin?

Thanks!

I'd recommend a $50 Pixel intervalometer. It's wireless RF and has sweet range. Save the arduino for another project.

I got exactly the same problem. Is ordered a cable and connected it to the arduino. Check out this website for more info: http://www.doc-diy.net/photo/remote_pinout/
My problem is that simply connecting the arduino pins directly to the cable pins doens't work. Someone told me to use a transistor but I don't know how...

My temp code is like this:

digitalWrite(shutterPin, HIGH);  
digitalWrite(focusPin, HIGH);
delay(200);
digitalWrite(shutterPin, LOW);
digitalWrite(focusPin, LOW);

Well, the problem is likely to do with the ground. What you want to do is short shutter and focus to ground. Use two SPST relays, powering the coil with the arduino, and wiring ground to one contact, and the other contact to focus/shutter.

Thanks for the link - this makes the job pretty simple, I think. At least, it makes the taking of photos simple. Now to pair it with an LCD and some input keys so I can change the intervals

I'll check that out - seems pretty cheap, actually. Thanks! Actually - got a link for that?
