LED Robot Ornament

Make a simple circuit robot Christmas ornament.

LED Robot Ornament

Crafting under pressure is irresistible. This year the Craftzine gals suggested an ornament swap– 12 days before Christmas. With a lot on our plates we all agreed to make time for crafting eight handmade ornaments each, and the deadline made it even more intense. Cheers to speed crafting!

  • On the back, twist the two long leads (+) together, and twist the two short leads (-) together. This is called wiring the LEDs in parallel.
  • Look for the (-) symbol near one side of the battery holder. Stack the holder on top of the LED leads matching + to + and - to -.
  • The circuit is the same as my LED shoe clips project as well as my firefly embroidery project.

  • Use pliers to twist the LED leads around the battery holder legs, and insert a battery to confirm the circuit illuminates the robot's eyes.
  • Use hot glue to secure the battery holder while it's still on.

  • Slide a strip of paper between the battery and the holder to provide a pull-to-start tab.
  • Insert the battery in the holder, pinching the paper strip between.
  • Write "pull here" on the paper strip.
