아두이노를 이용한 자동 시리얼 디스펜서 개발 연구

Auto cereal dispenser research and development using Arduino

Arduino is a simple open-source physical computing platform, it is possible to develop an interactive device to suit your individual goals and purposes through a variety of sensors and programming. In this paper, by using the rotation angle of the servo motor and the distance of the ultrasonic sensor, to develop an automatic serial dispenser. Ultrasonic sensors are the object comes within range 5cm to follow in real time the distance of the object (the bowl), The servo motor rotates the wings should be able to automatically distribute cereals. Through this paper, we contribute to the development of more useful product life.
