Abstract Abstract Abstract Abstract

The aim of this project is to design and implement an electronic musical box based on a microcontroller .

Most of the people listen to the musical box .The first impression is a revolving baby doll accompanying with the amazing music .Apparently, This is really monotonous .

In order to design a colorful and versatile electronic musical box ,the dot matrix LEDS are replacing the revolving baby doll . In this project . The musical codes is stored in the memory by table form . Finally , the circuit scheme , circuit layout and printed circuit board are presented . Moreover , the experimental results are demonstrated in this project.
