Sometimes we wonder what folks do with the Xbees and kits we sell, and sometimes we get to see the fantastic project, like this one! Arduino-based laser controlled wireless automatic cat food dispenser. Andres writes -

I have spent the last several weeks building a device to automatically dispense dry food to our two adorable cats. The cats need to be ona diet due to weight issues. So a certain amount of food must be given to them throughout the day.

i learned about the Arduino board soon before starting this project. So this little hobby has given me the perfect opportunity to learn more about this amazing device and its ever-expanding capabilities.

The cat feeder is basically a cylindrical container that has an opening on its side. The cylinder rests on its side and is supported by wooden dowles and rollerblade ballbearings which allow it to rotate with ease.

The rotation is provided by a wheel attached to a small motor. the signal and power is provided by an Arduino Duemilanove.
