Swatch Type:

The Swatch Type which would be utilized is an Actuator.  Where the button is the main material which would be used to conduct the experiment as it is the main outreach for the LED lights to blink and switch on.


The Swatch I made called “Light up Scarf” as brings up a fantastic outreach through the help of the design I created using the Yarn for crocheting with a mixture of the LED Lights, love creating new things and the experiment I created through Arduino, led and button brings out a good outcome as a whole. Where this creation could be made in many ways such as Keychains, Phone covers, and many more. I made this swatch little simple as I improvised from my previous experiment created. Last minute I made something creative using Christmas plastic balls and covered with thread around it. I stitched on the end of my scarf I made, and the LED lights are inside the Christmas lighting. I wanted to make something more creative and I attached the LED through the Jump Wires.


  • Arduino
  • Jump wires
  • Breadboard
  • led lights
  • Resistors
  • Button
  • Sponge
  • Yarn
  • Yarn Needle
  • Cotton
  • Christmas Balls
  • Thread
  • Hot glue gun


Tools & Techniques:

A technique which I have used to create my swatch is Crocheting and Knitting for attaching the Christmas balls on the scarf.

Tools which I used is Crocheting thread (Yarn), Yarn Needle and Crochet Hooks, thread for covering the balls.




These are the materials which I used to create my Swatch


It took me 3-4 days to create this Crochet Design. It is my first time and found this creative as well


Using my materials, I attached the Jumper Wires, Led Lights and Resistor.


I started coding on Pastebin and understanding about the fade and blink for my LED Lights.


After trying the code, I realized only 3 Led lights were working as a whole, reviewed and I did a mistake in my codes.


After my mistake, I realized that some wires and other Led lights were not connected correctly. I reviewed and made my diagram again.


I was testing with my Crochet Material how it would look. This is the way it will be with changing colors.


Last-minute planning by covering Christmas balls using thread and I covered with hot glue and left it for 3-4 hours and this is how I did it which would be a decoration for the scarf. I attached a hook for the LED light.



I stitched the decoration I made on the ends of my scarf through the help of knitting using a needle and thread.


After completing my experiment I tried it on myself, I do like it and looks cool.

“Arduino Fade In and Fade Out an LED – Tutorial #2.” ElectroSchematics.com, 1 Aug. 2013, www.electroschematics.com/arduino-fade-led-in-out/.


“Arduino – Button – LED: Arduino Tutorial.” Arduino Getting Started, arduinogetstarted.com/tutorials/arduino-button-led.

I was really inspired by the tutorials above as I made a lot of mistakes even by following the procedure, but I realized that I should do the experiment in a calm manner and follow the steps carefully.



Additional Notes:

My main objective is to expand and improve from my 4.2 experiment where I used the example which I made using a jar and cotton. I felt that that example would have a great outreach as a whole as I designed the main part of the swatch which would be crocheting. I wanted to improve this particular example because I had different ideas where I brainstormed through the image shown below. I ensured that I could create something where it would be kind of a DIY for others where they could make so many things such as Keychains, Covers, etc through different manners using these materials which I have used for my swatch. For myself the swatch I made I could use it as a Light up Scarf.


I wanted to make something through the materials I have with me and I feel that this particular Swatch I made was something little different especially by the crocheting work I did, and it is my first time making this as well. I have learned a lot about how to create something with the use of Arduino, led, etc. I followed the main part, which is adjusting the materials together, but my codes are different, and I tried many ways which are through the help of batteries where you won’t be able to connect to the computer but sadly did not work out. Therefore, as a whole, I feel that what I made was through my hard work and trying to make something new. I watched different tutorials and created what I felt would be beneficial. The mixture of the yarn and led lights I made gave a great outreach and I loved my final outcome. I made last-minute additional materials for my experiment using Christmas Balls and thread. Where I stitched on the ends of my scarf and made it look more stylish. These could be worn in your own manner and I wanted to use different materials and I made these all through my understanding and knowledge of creation.



Iris Andrici’s Story Book QR

Welcome to Witchlandia AR Popup Book and an Interview with Iris Andrici

By Alfonso Benitez



Iris Andrici’s QR story book  follows the story of a little witch as she explores a new, Wizard of Oz-esque world. As always, the illustrations that the creator makes are absolutely stunning. Having insider information, Iris Andrici disclosed that this project was inspired by her fascination with popup books. She believed combining popup books with AR would not only make the experience portable, but provide a totally new form of storytelling.

So how was the experience of creating this AR filter? Below is the exclusive interview conducted with her:

A.B: So what about popup books, you know, fascinates you?

I.A: What fascinates me about popup books is the popup feature that they have because it changes the way that something is being told. Something popping up already makes the illustration and visual aspects of the story more interesting than what is being written there. The writing aspect of it is just an addition to what the pictures are already making wonderful. On the other hand I also like the potential of interactability that popup books have. For example, you have sliders that allow houses to move or to change to colors of their windows, etc,etc. I really enjoy that. I think it is really fun, particularly for children, but also I think it can be turned into something fun for adults.

A.B: I know when you were finishing this project you suffered a lot of complications, do you still think you were able to emulate that exact emotion with your final AR project?

I.A: I don’t think I was able to emulate that exact kind of emotion, almost at all. I am quite disappointed with how it turned out. But the general animation managed to incorporate how a popup book feels when it comes up, but I would have liked something more explore able. I would have liked for my layers to be animated thoroughly and for you to kind of move around them as you change your phone. It didn’t even need to necessarily be in 3D, I enjoyed the aspect of it just popping out of the picture itself but I would have still enjoyed something where maybe you can zoom into the world, or choose to look at a specific window and see somebody do something inside of a house.

“I like the interactability  that popup books have” – Iris Andrici

A.B: I know you just said that you had a lot of qualms a lot of things you’d like to improve with your project, but what about it do you pride yourself with this project?

I.A: Surprisingly it’s not the AR part of it, it’s actually the fact that I learned how to animate it properly in After Effects. I would have liked to use Adobe Aero, but I had to change to… scri-script-hows it called?

A.B: I don’t know what you’re trying to say.

I.A: Hmm? The app you used!

A.B: Oh! Spark AR?

I.A: Spark AR (chuckles) There we go, I mean,  I wanted to used Spark AR originally, but, umm, but it doesn’t support the files that I needed and that I created and if I were to make it in separate layers I would have had to learn a bunch of ways to make a simple animation which just wasn’t worth the time or effort – when it can be so easily done in a program like Adobe Aero.

A.B: So what program did you use in the end?

I.A: I ended up using something called ROAR, which is an online media which is mainly used for marketing. So it was very limited, unfortunately. If I knew that beforehand I would have made my drawings far more colorful rather than as dark as it looked, because it [ROAR] had some sort of features that I could have made  the background transparent and maybe I could have added more little things on top of it by cutting them out like that. But unfortunately I did not know up until the point of using ROAR.

A.B: That’s awesome though.  Final question, what was your inspiration for the story? This little witch girl that was exploring.

I.A: (Chuckles) There was no real inspiration behind it, I just kinda like witchcraft. I guess it’s just part of the blood, coming from Romania and everything and therefore I created a character around that sort of world. But also! The city that pops up around is kinda sci-fi (laughs) so you can obviously see my inspiration does not have a specific narrative. It’s just something cute

A.B: I found it pretty awesome though. Thank you so much for your time!

I.A: Thank you!

It is clear that this AR lens requires a lot more work. However, it is this raw potential that draws me to Miss Andrici’s works. I, too, think this story board needs some touch-ups and modifications, but I strongly believe that it is in a good starting position. With enough work and love, I think this little witch girl’s story can come to life. Needless to say Iris Andrici, much like her protagonist, faced many hurdles; uncharted software, horrid paywall monsters, and her own frustrations. Yet in the face of these obstacles she managed to produce a beautifully illustrated page of (hopefully) a future Alternate Reality popup book soon to join your phone. I, her number one fan, cannot wait. Until then, I suggest you follow closely with her illustrations and other art-based projects with great anticipation.

Alfonso’s AR Project: Test and interview

This is Alfonso Benitez’s AR project. His experience is supposed to cover the Filipino traditional prop, the parol. Through this experience you get to place your parol in the world and learn about its significance.

I believe it is a very adorable project. While not as complex as other projects I really believe it has both a wonderful concept behind it as well as a pretty good result. It is a nice approach to culture particularly during the outbreak of a pandemic.

All of his assets are personally made which I also found impressive and respect in his work.



IRIS: So, Alfonso, how do you feel about your project?

ALFONSO: My project came out really good but I feel like there are a lot of improvements I could have made. I , however did not have time to implement them. 

IRIS: Alfonso, what would you have liked to implement that did not come out in your AR experience?

ALFONSO: Well you see (comma) Iris, there was meant to be a particle effect that came out with the p.a.r.o.l (teaching me how to pronounce/spell). I feel like a lot of the PAZZAZZ that was meant to go in this final sequence of events didn’t live up to what I was expecting because they were not implemented. I am however very, very proud because I made the model myself, with great amount of pain and help from my friends.

IRIS: What was the experience you intended for the audience?

ALFONSO: Well you see, Iris, I wanted to share with this class and some close individuals, like you, about my culture and what we do in the holidays. The process of making parols is typically done with close friends and family. Since I can’t be home due to COVID I decided to create this digital experience with my friends and peers. 

IRIS: Overall, how would you improve this project if you had either the technical skill or time to do so?

ALFONSO: There are a lot of things I feel I could have improved, namely everything. If we are being specific though, I would have liked it to be more interactive. The most this experience cane do is educate people but, I would have liked for people to make these parols, to colour them and decorate it. I hope there is a person out there who has the resources and abilities to do a project like mine and can educate people on the various cultures of the world. 

IRIS: Thank you for your time, good job on your project, very lovely theme!


Fabric breadboard & flower vibration sensor





Flower vibration sensor

• As long as the sensor detects the vibration of something, there will be a signal output. I made a simple vibration sensor through a ball switch, and combined the vibration sensor and LED. When the sensor detects the object vibration, the LED lights up, and when the vibration stops, the LED turns off. I use fabric to wrap the ball switch into a flower. When the flower swings or there is any vibration, the red LED on the fabric breadboard will be lit.


A list of materials I used

• 1× Ball switch SW200D

• 1× 5mm LED light

• 2× 220 resistor

• Pink cotton

• Wallpaper knife

• Needle

• Conductive copper tape

• Copper wire

• Ruler

• Battery

int SensorLED = 13;

int SensorINPUT = 3;

unsigned char state = 0;

void blink();

void setup() {

pinMode(SensorLED, OUTPUT);

pinMode(SensorINPUT, INPUT);

attachInterrupt(1, blink, RISING);


void loop(){


state = 0;








void blink(){




Source of inspiration:

• The breadboard is conductive through the bottom, and there are many sockets on the surface to connect the components. And the fabric I chose can also have many sockets, just install the conductive device at the bottom to make a fabric breadboard.

• Flowers can sway with the wind, but when the wind is small, it is difficult for us to judge whether the flowers are swaying with the naked eye. So I use the vibration sensor made by the ball switch to sense whether the flowers are swaying or swaying. The red LED light will light up.

• If the Fabric breadboard is used on the clothing, the device can be installed on the clothing and the clothing can be decorated, and it is also practical.
