Abstract
Automatic cat feeder based on fuzzy logic control is designed to maintain healthy nutrition in cats so that they are maintained and it can provide convenience for cat owners. Furthermore, the sensor is used as the input value in order to obtain the output value after processing by fuzzy. The resulting output value is based on logic. Meanwhile, the value of the cat’s food portion is based on the calculation of the dose taking into account the cat’s weight and condition. In this study, the fuzzy type used was the Mamdani method with two inputs and one output. The volume of cat food would be detected by using an ultrasonic sensor by utilizing reflected waves while the weight of cat food would be detected by using a weight sensor (load cell). Moreover, the output obtained is the time the servo motor valve opens to remove the feed into the feeder. The results of this study are obtained from hardware testing, software testing, and mathematical calculations based on the centroid method. Hardware testing uses Arduino Uno while software design and testing uses tool box.
