아두이노와 초음파센서를 활용한 거리인지 크리스마스트리 개발 연구

Case Study on Treatment of Pancreas cancer in Drama

Ado~uino as a simple open-source physical computing platform, it is possible to develop an interactive device to fit the individual purpose and application through various sensors and programming. In this paper, by leveraging the Abudo~uino and ultrasonic sensor HC-SR04, it tries to develop a Christmas tree on which to perform the cognitive to operate a certain distance. This tree is a constant distance is recognized to sound and movement, so as to perform operations such as change of the LED pattern. Ultrasonic sensor, as by detecting the distance in front, the piezoelectric buzzer can be used as an element for operating the detailed function of the tree, which uses a servo motor is used for the music performance, and gives movement to the tree to. Through this research, and to be able to contribute to make a creative room accessories that utilize Abudo~uino and sensor.
