Abstract
In this paper, a smart alarm clock music design. This design is from the central controller, the clock system, monitor and keyboard parts. Controllers using SCM AT89C51, the clock system uses the U.S. company's DS1302 DALLAS real-time clock chip, it will have the time to signal transmitted to the microcontroller, SCM through 74 LS48 decoding, LED 8 of the digital display of the current Time, When in the course of time set by the arrival of the alarm time, will play music, and at this time of the LED digital display is no longer time but a code that only users of this code from the keyboard on the correct input into the Music can be closed, otherwise, would have been broadcast on music. Users can set the alarm through the keyboard of the time and correction time.
