Cat Feeder Project - 1.0
(Concept Design, Electrical Circuit Design, Programming, Testing )
Embedded Files
The pet feeder (Cat Feeder) is an automated feeding system enables the user to set specific interval of time to control automatic portion control device in which the owner prescribes the amount of food and then there is the variety that ensures that there is a constant amount of food in the feeding cavity at any time.
I have drafted several changes to the product to improve it by either reducing failure or enhancing it with greater functionality.
Version 1.0 Include three different feeding times which can be defined by the user, error checking mechanism Arduino timer is used without any external time keeping mechanism
