Automatic Carrasius Auratus Feeder with Water Changer Mechanism

The purpose of this study was to create and design an autonomous fish feeder system that uses an Arduino Uno microcontroller and has a water filter and water changeover mechanism. The Arduino Uno microcontroller activates the automatic fish feeder system, dispensing the necessary quantity of fish food with the help of a servo motor. The turbidity sensor is included to determine how cloudy the water is and to look for any contaminants. When the turbidity levels rise beyond a certain point, the submersible pump is turned on to start the water changing operation. The water filter is used to clean the water and get rid of any pollutants. The system was put to the test in a 2.5-gallon goldfish tank, and it was discovered to be effective at providing regular feeding schedules while maintaining ideal water quality.
