PIR sensor, motion activated halloween scare prank

Courtesy/Thanks to: Anything Arduino

Description: In this episode we hook up a generic mp3 player to an Arduino to give projects the possibility to play sounds. This particualar project was done to give my Halloween scare prank some sound. Instead of using an MP3 shield we use a generic mp3 player bought on ebay for about 3$. It works great when you just have one sound you want to play. Check out the previous episode for how to build the first part of this circuit:
