Secure Fish Feeder : Automatic secure fish feeder to make sure you do not overfeed your fish

Abstract: This project aims to provide fish keepers with a safe and simple way to feed their pets while abroad or in any other situation where they do not have the ability to feed their fish by hand. Overfeeding is an unfortunate albeit common reason for mass death in an otherwise safe and healthy aquarium. While overfeeding to land dwelling pets might have negative health implications, the rapid damage seen in an aquarium is unparalleled in other environments. This is due to the release of ammonia that occurs when excess food (and partially fecal matter) is decomposed. Moderate feedings provide adequate nutrition for the pets, while keeping ammonia production at a level where it can be converted to nitrite and lastly the rather harmless compound nitrate. Most, if not all, feeders on the market today base their feedings solely off of volume, but this can lead to large variations in feeding size, due to variations in air between pellets in the feeding portions. By adding a failsafe with weight, we can fully prevent any chance of overfeeding, and thus ensuring a long and healthy life for our pets. Overall the goals of a safe fish feeder were accomplished, although the weighing was not as accurate as it optimally would have been.
