Get into the holiday spirit with these Arduino-controlled light shows

These Makers channeled their inner Clark Griswold and adorned the outside of their homes with Arduino-based lighting. 

“250 strands of lights, 100 individual bulbs per strand, for a grand total of 25,000 imported Italian twinkle lights… 25,000 lights. I dedicate this house to the Griswold Family Christmas…Drumroll, please…Drumroll…Jooooooy to the worldddd.”

Just days before all of your friends, loved ones and Santa arrive, Christmas and its twinkling light spectacles are well underway. And really, what could be more appropriate for Makers than a set of artfully strung, decorative LEDs controlled by an Arduino? For those looking to channel their inner Clark Griswold and adorn the outside of their home with hundreds of bulbs, here’s some holiday inspiration!


Over the years, a number of DIY enthusiasts have turned to the easy-to-use Arduino Uno (ATmega328), Yún (ATmega32U4) or Mega (ATmega2560) to drive their impressive displays — some of which would put “Sparky” to shame.

Then, there’s always that one neighbor who does their best to keep you from getting into the spirit. If you’re like Clark and have a Todd and Margo Chester of your own, you’ll get a kick out of what one Maker did to get back at those next door in a very subtle yet ingenious manner. Using an Arduino Uno (ATmega328), the Instructables user “ywyjrgrasc” decided to program his lights to blink an insulting phrase in Morse Code. (#GeekMode)


And for the Star Wars fans out there, this is an added bonus is for you. Although it may or may not be powered by an Arduino, this clip from ABC’s Great Christmas Light Fight will certainly awaken your holiday decorating force!
