Motion-activated Sound Effects with Arduino, PIR Sensor & MP3 Player

My Arduino tutorial will show you how to create spooky sound effects triggered by motion using a PIR sensor, MP3 player, and Arduino Uno! Learn how to wire a PIR motion sensor and mp3 player module to an Arduino Uno and then write Arduino code examples with me to trigger a variety of sound effect based on motion.
