Susan’s Halloween costume

So from this week, I had my updated version of halloween costume design, which is a combination of “demon mask” and “Rainbow sweater”. The reason why I come up with this idea is because I was considering to put the packs in an appropriate place, which is in the hoodie and the pocket of the sweater! So as the drawing shows, the design part are A and C. I have been discussed and suggested of better connecting solution and better sensor/switch to use by classmates and Becky, which is really helpful!

Yiwu’s Hallowenn custom

This dress is a cloak. At the beginning, I wanted to catch the light. Because light will slow down in special materials. I think we can have a material that can slow the flow of light so that the human eye can see it?
In the end I found it impossible, at least for now. So I want to use leds to simulate the flow of light. Then put it in the clothes.
After this idea was formed, because I had referenced the code of the project I was wearing on my head, the code of this project did not seem to change. I thought about how to change it. So I decided to add a sensor. Let it make some changes. Finally, I decided to use a sound sensor to change the light state according to the size of the external sound.

I used the RGBW light strip and sound detection module. I also bought a super large battery.

As for the Arduino technique(s) I’m using, I will combine the light drop and rainbow in the Arduino code.

Qiting’s Halloween Custom

I plan to make a black wedding veil(hair pieces) and dress it with red led. I want it light up when slightly wobbling. It’s a vampire bride costume so that I also want to add two ghostes as decoration. In order to do this, I would need:

  1. Vibration sensor switch(5 different types for testing, SW-18015P/SW-460D/SW-1820P/SW520D/SW200D)
  2. Led strip(ws2812b)
  3. Black wedding veil(hair pieces)
  4. Ghost toys decoration
  5. Wire
  6. Battery
  7. Hot glue
  8. Felt fabric

I found a tutorial on how to use the vibration switch. Basically, it just a switch that triggered by shaking. The connection method is the same as a normal switch. The sensitivity and the pin of each vibration switch are different, so that I brought 5 different types to test which one is more suitable.

Pumpkin Cloak

My idea is to design a cloak with pumpkin features and lighting effects with Arduino. It was developed from my idea of a pumpkin scarf. I didn’t find any material is suitable for a scarf, but discovered a black cloak I bought for a school performance. My design shift from scarf to a cloak, I was going to add leaves on the top of the shoulder area with green LEDs inside. In front of the chest, I would make three to four different sized pumpkin plush, with yellow LEDs inside. These pumpkins would be sewed on top of buckles on the cloak.

touch sensor

For Arduino, with the help of touch sensors, yellow lights inside each pumpkin would blink randomly once you touch them, to create the effect of dimly lit. In terms of coding, I was thinking of making adjustment based on the examples of the blink code.



Above on the left is image of cloak I will be using in the design. For creating different sized pumpkins, I bought this kind of fluffy cloth on the right. With polyfill inside, I also ordered black materials as their eyes, which are still on the way.


Katy’s Halloween Proposal

I wanted to use materials I already have from the plush night light project. So in line with the yellow theme, I am making a sunflower headband. There will be a flexible led strip encompassing my head and the ends of the leaves will have led lights connected to buttons.

For this Project I will need:

  1. Led strip (
  2. Flora controller (
  3. Buttons (
  4. Battery pack (already have)
  5. Resistors (already have)
  6. Led lights (already have)
  7. Elastic band (already have)
  8. Yellow fabric (already have)
  9. Polyfill (already have)
  10. Stiff green felt (optional)
  11. Darker yellow felt for texture (optional)
  12. Snap enclosures

Codes work and now I have to figure out how to combine code.

Halloween Costume Project Proposal – Anne

I will be making a light up talking sorting hat based on the the one in Harry Potter.

The first two images are the ones I am using for reference. The last image is a “sorting hat” I purchased online. The hat is not only too big but doesn’t read as a sorting hat – there is no distinctive grouchy face. However, it’s the correct colour and there’s enough material to pull it apart with a seam ripper and re-cut and reassemble it. I’ll make an armature out of chipboard, wire and polyfill for the distinctive brows and mouth.


  • 2 eyes that light up and are animated
  • 1 led in the mouth cavity that lights up with the eyes (TBD if this animates the mouth or is just weird).
  • “down lights” that wash over the wearer’s face when the eyes are lit. Colours will correspond with the Hogwart’s House the hat assigns
  • a “voice” that is activated and plays after the eyes are lit

Circuits, Psuedocode and Code resources


When vibration detected, neopixel jewel eyes light in animated sequence. Once eyes are lit, voice is activated and plays a .wav file from a selection of .wav files (if included in the final sketch, the mouth area led lights). As voice is talking, a secondary downlight from bright leds wash over the wearer’s face.

That said, two different boards will be creating this illusion. The Arduino Uno board will be used for all the light effects. The second board — the Adafruit Audio FX Sound Board will be on a separate trigger and will serve up the sound files.

Circuit for NeoPixel

Circuit for Audio FX Sound Board and Speakers

Tinkercad does not have the parts for the sound board. However, what is key here is that the FX Sound board is a standalone sound solution that does need Arduino to run. Just hook up to power and speakers and attach a trigger switch to play the .wav files.

Here is a sample of what the FX board circuit looks like that will be modified for this project:


(2) neopixel jewels for the eyes

(2) neopixel 60 quarter rings for the under hat brim down lights

(1) Adafruit Audio FX Sound Board (part #2217)

(1) either vibration switch or simple on/off switch

(1) floppy hat to pull apart and rebuild

(2) ping pong balls for diffusing the eyes

(1) translucent shimmery fabric for over the eyes for effect

chipboard, wire and polyfill for forming the brows, nose and mouth

(2) battery packs

vibration switch (to trigger lights)

membrane led keypad (single key to trigger sound)

Arduino Uno board

permaproto breadboard

Stephen’s Fly Idea

For my Halloween costume idea, I would like to do be a radioactive fly on Mike Pence’s head.  I am going to use two neopixel rings centered on the back of bug eyeglasses. I intend to use a tilt ball switch, so when I tilt my head up and down the lights sparkle on and off.  I plan on having the wires run along the inside of the glasses and down the back of the neck.  

I ordered my glasses, but they have already been delayed in shipping, so I may buy goggles instead.  I am going to need 2 neopixel rings, 2 resistors, wire, 1 tilt ball switch, hot glue, and black tape.

I am open to reconsidering the interaction and the switch decision.  I am also open to exploring the idea of antennas.  I am not exactly sure that is what I want, but it might need it to look more believable.

More Halloween

Two circuits

For my Halloween costume I would like to place a NeoPixel Strip, with a Gemma and battery holder/switch inside a small witches hat. That is what the circuit on the left represents.

The circuit on the right will be attached to a cape. I will make 4 holes through the cap to bring the wires from in “inside” out, and I will sew plastic spiders onto them. I hope the LEDs will light up the spiders nicely and they will compliment the cape.

The materials I will be using for this assignment are two batter holders with switches, (I will experiment with using a separate power source and a independent switch), 4 LEDs, 4 resistors, wire, 1 neopixel strip, 1 gemma (if I am able), hot glue, thread, and needle.

Zekun’s Halloween Costume

I want to design such a headpiece because my crystal ball nightlight can fit in the Halloween context very well. I want to find a way to include it as a part of my Halloween costume. Therefore, I decided to make this headpiece for psychics. I want the LEDs on the headpiece to gradually shift from pink to green to match my crystal ball’s iridescence. And the NeoPiexl Jewel will have a different lighting effect than NeoPixels, but I haven’t decided what will be.

I find this introduction to NeoPixel Jewels

And I tried to combine this code with what we did last week in this tinkercad program.

Isabell’s Halloween Costume

Vampire Costume

I have decided to make a vampire costume so I want to boldly use the colors red and black. The black cape costume will be made and the red colors will be covered with RGB LED lights. In order to do this, I would need:

  1. Black Cape: Black fabric
  2. RED RGB LED strips:
  3. More wires:,8088:A,9266:C,8091:A,8534:A&rmdValue=p98277150:vt-1.0.0:p209460023&isAddedCart=

All my materials are on its way.

The black cape will have the ends of the sleeves to be lit up and the hood of the cape will be lit up. If possible, I will try to use LED strips to be a possible belt.


I am not 100% sure about the circuitboard and not sure how to connect multiple strips. But with the most recent lesson from LED strip soldering lessons I will use the technique to lit up the RGB LED lights. I would need a specific code as well to make sure my LEDS are red.
