This year my house was illuminated and animated by spooky music thanks to the Raspberry Pi. Back in 2009 I created what I called the x-mas
box which housed 8 solid state industrial relays connected to an arduino. For this year I repurposed the box and used the Raspberry Pi instead. The lights and music where triggered by a PIR motion sensor.
The show was part of my SMS Magic Mirror with Automatic Candy Dispenser project (Instructable not ready yet, stay tuned).
