WAV file player

This is a .WAV file player using an Arduino UNO, a micro SD card reader, a speaker, and a transistor to amplify sound. The sounds are recorded using Audacity. I replicated this project from Max's blog. http://maxoffsky.com/maxoffsky-blog/how-to-play-wav-audio-files-with-arduino-uno-and-microsd-card/ http://bryanduxbury.com/2012/01/20/one-transistor-audio-amplifier-for-arduino-projects/ https://github.com/TMRh20/TMRpcm/wiki http://www.dx.com/p/micro-sd-card-storage-memory-board-module-for-arduino-146706?Utm_rid=52746118&Utm_source=affiliate#.VdoFK5fAoQs The wiring for the micro SD card reader goes: 3.3v goes to 3.3v on the Arduino UNO (for power) GND goes to Ground on Arduino UNO D0 goes to pin 12 on Arduino UNO D1 goes to pin 11 on Arduino UNO (The D1 MOSI)in back or CMD in front CLK goes to pin 13 on Arduino UNO D3 goes to pin 10 on Arduino UNO
