To save the effort of getting up at sunrise to let the chickens out, instructables user Robot Chicken has designed and built an excellent chicken coop door controlled by an Arduino, the motor from a power tool and some simple circuitry. This is a prime example of the level of automation and control that can be achieved with the Arduino platform.
Now all the user needs is a deterrent device for foxes and the setup would be complete. To get started with your own automation systems, consider using the Freetronics Eleven - the Arduino-compatible with onboard prototyping area, and our LCD Keypad shield, which makes using an LCD very simple:
