Abstract

A portable MP3 player with standard functionality is being designed and built. The central mission in this project is to create the portable MP3 player with a low cost and with attributes such as small in size, lightweight, durable, high performance and long battery life. This player enables a user to play and share music with friends anytime and anywhere they want. From a hardware perspective, the major devices include the PIC microcontroller, MP3 decoder chip, SD card or multimedia card that is function as storage. Microcontroller is the heart of the whole design. It control how data flows and send the song which is streamed serially from the SD card to the decoder. The decoder converts the digital stream to the equivalent analog signal. After being amplified this analog signal is the sound that we can hear. From software perspective, all components must be programmed to successfully function with one another to produce the desire output. As for default capabilities, the product will embody the same default function as other portable MP3 player as available in the market today. These include creation play list, skipping forward or backward, pausing and stopping song.
