Bajdi built an Arduino MP3 alarm clock and wrote a detailed explanation on his blog describing the build: The idea is simple, an LCD that shows the date and time. A couple of buttons to set an alarm, and an MP3 module and small speaker to play an MP3 when the alarm goes of.
Ivan Creations wanted to use his old car cassette player (that sounds descent) to somehow play MP3 files. He devised this hack using PIC16F877A to control CECL08D MP3 player and Grundig WKC 1704 RDS Infomat Cassette player with remote control via Blaupunkt RC10 remote. “The MP3 player output signal is hooked up to the cassette […]
David Mellis from the Arduino crew presents this tutorial on playing short audio samples using only the Arduino and a simple speaker. Using the PCM Library for Arduino, this project takes a short (4 second) audio sample of your choosing which you encode on your PC into MP3 format (down sampled to 8 KHz, 8-bit […]
