Trick or Treat — it’s Arduino! #WearableWednesday #ElectronicHalloween


Okay, you all know I love Arduinos in all shapes and sizes, so I just had to get all giddy over this costume that I found on Bits & Pieces from the Embedded Design World. Not only does it have LEDs, it also details the pinout for real connection fun. Of course, the neighbors won’t know what you are unless you live on a tech campus, but you’ll probably still get candy just for being so colorful.

This masterpiece is by Angela Melick, mechanical engineer and cartoonist (in equal proportions). She started with puffy fabric paint for the details on the shirt, which is not easy when you are doing text. Then she worked on the function of the Arduino.

The lights down the side blink to a pattern I programmed and are powered by the Arduino around my neck. The wires along the side were glow sticks and represent the tangled mess that any Arduino project is in its first stages.

On the table, I have to agree that Arduino projects do resemble a tangle. Got to love those large LEDs.


Angela was pretty excited about the set-up as well.

This was my first time soldering “free” wires and 8/8 of the LEDs worked, which I’m very proud of because the wires go all the way down the side and all the way back up the shirt.

With all of those wires connected, it must have become apparent to Angela that her top half was missing out on some costuming fun, so she decided to make a matching Arduino fascinator. It’s so cute and is packed with another microcontroller and blinky.


So, not to make you nervous, but Halloween is just a few days away. If you have an existing Arduino project around the house, just deconstruct it and work it into a sweat jacket to make your own costume. Maybe you can even use some iron-on lettering to make the pinout. If you are itching for some new parts, why not make our Space Face LED Galaxy Makeup. You’ll definitely have the best wearable tech in the room.
