Description

Because of working memory space constraints in Arduino microcontroller boards, production of sound with these boards is normally limited to creative application of beeps. Connecting a SD card based MP3 player to an Arduino overcomes the memory limitation and opens the world of real digital audio. Here we discuss a Music Machine consisting of a simple stereo MP3 player that is controlled by an Arduino Nano. A connected PAM 8403 mini amplifier powers two mini speakers.
