PAM 8404 Audio Amplifier module arduino




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.
