A digital clock with sound is a tool that can display the current time in the form of display that can be seen and can make a sound in the show hours. Sound settings in the show hours can be arranged on the working mode. Working mode is used among the sound will be played every minute, 10 minutes, 1 hour or as desired by users. Input section in the form of a button. Keys used to enter data and setting the time or the selection of working mode is used.
While processing part consists of the microcontroller AT89S51 as the main processor, RTC DS12887 is used in the manufacture of this tool to generate the timing presisi.baik minutes seconds month date and year in addition to microcontroller and RTC is required for storage media that is used ISD2560 voice. For the output of LCD and speakers.
