Nowaday, the semi-conductor technology and precision automation technology are become rapidly improving, so mechanical industries converting mechatronics industries which are combined mechanics, electrics and electronics. To manipulate these technology, the ability which can design precise machine and controller and the ability can program the operation software are needed In this study, rotary music player which can play the music, rotate the character and light the piano board according to the musical notes was developed. The concept design to arrange the piano board circularly was studied and the hardware technology with step motor control, photo sensing, serial port interface were used. And to generate the musical note, new conpact program for private use was developed. As a result, the rotary music player which is first in the worldwith for leisure was born.
