Automated goldfish feeder
thingiverse
Automated fish feeder. Glue hopper to base with superglue. Made to fit 9g servo, steel wire for push-rod. Controlled by Arduino microcontroller. My system uses an Arduino Uno with a real-time clock (RTC) module, programmed to activate at feeding time. Program Arduino to move slider to loading position (slider hole even with hopper), wait for food to fill, then move to dump position to release into tank. Repeat as necessary. Mount above tank high enough so as to not get wet/soggy. Designed for pellet-type food.
