The design and development of automatic fish feeder system using PIC microcontroller

This research devoted to reduce the labor cost as well as develop better pellet dispense system. Subsequently, this research was proposed to design an automatic fish feeder system using PIC microcontroller application. The device developed combines mechanical and electrical system in controlling fish feeding activity. This device, basically consists of pellet storage, former, stand, DC motor and microcontroller. The pellets controlled by DC motor which located under the pellet storage. A control system was then attached to this device allowing the fish to be fed at the right cycle time as required or predefined by user. Timer was employed in this device to control the motor rotation attached to sphere former, which dispense the pellets into the water. The pellets dispensed into the marking area of the pond based solely on the rotation speed of the motor itself. The controller came with a keypad giving user more option in determining the suitable speed for the motor depends on their cattle. In short, the pellets in the automatic fish feeder system will be controlled by the rotation speed of DC motor.
