    This study presents an affordable, easy-to-build demand feeder for fish food pellets. Controlled by a microcomputer, it reliably dispenses one pellet per motor activation, ideal for automated aquarium systems.

    Area of Science:

    • Aquatic Science
    • Engineering
    • Animal Husbandry

    Background:

    • Automated feeding systems are crucial for consistent animal husbandry.
    • Existing demand feeders can be complex or costly.
    • Microcomputer control offers precise feeding schedules.

    Purpose of the Study:

    • To design and describe an inexpensive, easily constructed demand feeder for pelleted fish food.
    • To enable microcomputer control for automated feeding applications.
    • To ensure consistent, single-pellet delivery.

    Main Methods:

    • Construction utilizing an AC synchronous motor and gearbox.
    • Integration with a microcomputer control system.
    • Testing with commercially available pelleted fish food.
