Picture of Raspberry Pi Halloween Lights and Music Show
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).

Step 1: Materials

  • Raspberry PI
  • USB Wifi dongle
  • Adafruit Rapsberry PI prototyping board
  • PIR Motion Sensor
  • Solid State Relays
  • 4 Flood lights
  • 4 Flood lights sockets
  • 1 Strobe light
  • PVC pipe elbow fitting
  • Speakers
  • Cables

Hi there,

I have been thinking about using Raspberry Pi for some time to do what much more expensive options do. Basically I've seen around the net these boards with pin wirings for like 8 inputs, 8 outputs, etc that cost > hundred bucks. I am wondering, with the python code, can you basically listen for 8 or so input triggers, and determine which trigger was tripped..and then run up to 8 or so outputs at once? Meaning.. assuming my Pi board is connected via USB to my laptop, can x number of inputs trigger multiple outputs at once? I know with the python code I can then run audio/video files if wanted, but just wondering if I can also turn on mulitple outputs on the board at once to say turn on a couple of lights in some sort of sequence, possibly two or three at once, etc.

Hi I am a beginner.


I would like to make something that will do the following.
press a button - sound clips play. then after a set time interval the power to a socket powering a light switches off. then after a set time interval another socket powering a smoke machine switches on for a short period of time. Then finally the power to the original socket turns on bringing the lights back on.
What would be the best way to do this? would it be an arduino with relays? or pic controller?

If i then wanted to make the above into a 4d cinema so it powers up a projector and plays a video file would i be better using something like a raspberry pi that can play video files itself? I would want everything to operate with a press of a button though and do not want to load programs up manually etc.

Thanks for your help

Yes for what you describe I would recomend a Raspberry Pi!
