## Ingredients:

- an Arduino Ethernet board
- a small stepper motor
- a double full-H-bridge to drive the stepper
- a reflexion sensor with LED and photo transistor
- some plywood
- four photos of your loved ones
- a black self-adhesive plastic film
- the webduino library from the Arduino homepage
- the Metro library from the Arduino homepage

The Arduino drives via the double full-H-bridge the stepper to turn 90° three times, 15 minutes between each turn. The fourth time, to complete the 360° full turnaround, its drives the stepper until ... the white mark arrives of the reflexion light sensor. This mark and the photos on the other side of the round piece of plywood have to be adjusted carefully, that way, that one photo appear in a window in the frontside of the wooden box. (Consider the photos of your loved ones where you see colored rectangles above.) Thats it. Code is here http://files.a385e-5.de/files/Bilderrahmen-0.9.tar.gz '
