How to Do Arduino-Controlled Intelligent Time-Lapse Photography

Project: Light-Sensitive and Adjustable Dynamic Time-Lapse Photography
 Arduino-Controlled Intelligent
By Holden Leslie-Bole

Approximate cost: $70 without the camera

I’ve been doing some time-lapse photography with my GoPro HERO3 for a while now, and I’ve gotten some great footage.  There have been times, however, when I’ve wanted to be able to use my DSLR to have more control over the shots that I’m getting.  I had the idea to use an infrared shutter controlled by an Arduino to be able to operate the camera remotely—I could put the circuit in a weatherproof box so that I wouldn’t have to mount it directly on the camera either.

I got to thinking that if I were using an Arduino, I could add some other cool features to my time-lapse photography rig.  One problem that I’ve encountered when doing GoPro time-lapse is that when I set it up for a sunset shoot, if I don’t time it exactly right, I may end up with a few hundred dark and uninteresting pictures.  I decided to add a photoresistor to act as a sensor of ambient light levels.  Depending on what threshold the user programs, the camera will start taking pictures when it gets light enough in a morning shot, or stop taking pictures after the sun goes down and it gets dark.  Feel free to play around with the values on this to get a light response level that suits your needs!

I also added a potentiometer to allow the user to control the interval between pictures on the fly without having to reprogram the Arduino.  This way, you could make the time lapse to speed up or slow down over the course of a shot for dramatic effect.  There is a multi-digit seven-segment display that shows whatever delay (in seconds) that the user sets.

Since many time-lapse enthusiasts are interested in adding a dynamic element to their shots, I included functionality for a servo-controlled rig that could allow the camera to rotate or pan across a scene.

This circuit is designed to be used with an infrared remote shutter. I designed this for a Nikon D3100, but any other DSLR with a remote should work just as well. In this circuit, an LED currently acts as a stand-in for the remote shutter, but adapting it for the shutter is only a matter of bypassing the button in the remote and controlling it with the Arduino. Since it is difficult to tell when an infrared transmitter is activated, the seven-segment display flashes each time a picture is taken to inform the user of its progress.

Overall, this project was designed mostly as an exercise in becoming more proficient with Arduino.  For that reason, I haven’t included any instructions for mechanical dynamic rigs, but if you come up with one, please link the design in the comments!  I’d love to see it.

Step 1: Parts and Materials

Parts list:Arduino Uno
Breadboard (or two if you need the room)
Jumper wires
10kΩ resistor
Camera remote shutter
4-digit 7-segment display (12 pin)
The parts for this project, with the exception of the camera and tripod, should be under $70.  The camera will obviously be more expensive, but I am not including that in the cost of this project.If you choose to use the servo to develop a dynamic mechanical rig, then the cost may end up over $70 as well.
