Here is a little project I've made 2 weeks ago : a timelapse controller for Canon DSLR.
It's pretty simple
- an arduino mini pro
- 2 optocouplers (4n35)
- an LCD (HMC16223SG - controlled by HD44780)
- three push buttons
- two LEDs
- a bit more than 600 lines of code (not really optimized, nor commented, nor cleaned ...)
You can find more details on my blog which is now available in english (http://domoduino-world.tumblr.com/
) or in french (http://domoduino.tumblr.com/
And the first two videos I've made with that timelapse :
