Raspberry Pi Halloween Lights and Music Show

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).

Check out instructions on how I build the x-mas box here.

For this project I decided to only use 4 of the 8 solid state relays. I connected them directly to the RPI GIO ports and ground. I used the PVC pipe elbow fitting to limit the radius the motion sensor had. This helped to reduce "false positive" triggers since the PIR motion sensor can be quite sensitive.

I used a long cable to let me place the motion sensor close to the ground (the ssr box was placed on the balcony).

Thats basically it. I used the RPI GPIO ports
  • 17 strobe light
  • 18,21,22 flood lights.
  • PIRmotion sensor
    GPIO 23
    3.3v
    Ground

I placed the 3 flood lights on the second floor deck pointing upwards to allow reflection on the walls. The strobe light was placed in the first floor and it was turned on during the whole song duration.

I connected a set of powerful speaker into the RPI mini-jack audio out.
