How To Build The Xmas Lights From Stranger Things with Raspberry Pi


I’m a big fan of the Stranger Things series and I can’t wait for the next season. If you haven’t seen the show, in season 1 two characters communicate across different dimensions using Christmas lights with letters written underneath them. 

I built a replica of this a year ago, but with the upcoming release of season 4, it’s time to build a bigger and better version. These lights can be hung up on your wall, and can let friends, family, and even strangers communicate with you.

What You’ll Need For This Project 

  • Raspberry Pi 4 or Raspberry Pi 3 
  • USB power adapter for Raspberry Pi
  • 8 GB (or larger) microSD card with Raspberry Pi OS. See our list of best microSD cards for Raspberry Pi. 
  • Two strands of 12v WS2811 LEDs (one strand will work, but two looks better for letter spacing)
  • A 12 volt power supply (any standard 12v power supply will work)
  • Jumper cables
  • Wire strippers
  • Solder or wire nuts
  • A black and white printer and paper
  • Scissors
  • Push pins
