Don't forget to isolate the arduino signal from the camera !!!
Phone timelapses are so easy. But the quality of the image is sad. So I decided that I want to make one with my real camera. But wait I can't. So I made this little device.
It lets you trigger something, in my case the camera at an adjustable interval.
Don't forget to isolate the arduino signal from the camera !!! I used an optoisolator, but it should work with any relay like device.
THE OPTOISOLATOR between the arduino and the jack.
Arduino intervalometer 1.1
