In this paper, we designed a sound effect device, which was applicable forspray paint art process. For the applicability research of the device, wedesigned a prototype which had a form not far off the traditional spray cans,using Arduino and various sensors. Through the test process of the prototype,we verified the elements that would be necessary to apply our newly designeddevice to real spray paint art activities. Thus we checked the possibility ofvarious musical expressions by expanding the functions of the designed device.
