For those with unattended pets who need to be fed dry food, this project may be of interest. Damon has designed and built a simple food dispenser that is controlled via an Android phone running a scripting language, which commands an Arduino-controlled feed unit via bluetooth. Here it is in action:
Although this may seem like overkill, the use of the phone enables internet streaming of the vision from the camera, allowing remote monitoring of the food level in the feeder. To get started with your own Arduino-based projects, consider using our Freetronics Eleven - the Arduino Uno-compatible with onboard prototyping space:
