I was working lately on a simple peace of program to control my Nikon D40 by a PC. This little app communicates through my Arduino board with the camera. To get my d40 to capture something I used a bit of code from Gustav von Roth which can be found here. This Code sends a signal over an IR Led to generate time lapse effects. An example is shown below.

I captured about 1 hour with an interval of 1000ms in this example. The Code and Arduino Sketch can be downloaded from here. If you have any problems with setting this up feel free to leave a comment. The next Version will include some Servo controlling to move the camera while capturing.
