Materials Used:  Foil Paper,Scotch Tape,BreadBoard,Jumper wires,Resistor,Arduino. I used these materials because they were available at my home.I have previously worked with these materials and I was comfortable in making this sensor.

Images for the materials used can be seen at:         https://drive.google.com/drive/folders/1EMxXR8rU-S1HLrZChMdK7yNNiNf3-wYm?usp=sharing

This source was the original source that I took inspiration for making the Capacitive sensor.The sensor did not involve any expensive material.My whole ideation behind this sensor was an addition to my previous semester project which was a wall hanging without any touch sensor.This touch sensor completed a desired project.

The Light Wall hanging can be viewed here for better explanation:

These lights on the wall hanging can now be activated from the touch sensor I created this semester.I have attached the touch sensor behind the box.So whenever a touch is felt the lights go on accordingly .


Circuit Diagram: The Diagram shows the wire connections with the arduino.The connection with the sensor can be seen in the image below.Which clearly. shows how it is connected with the touch sensor.screen-shot-2020-12-11-at-3-35-34-pm Project Image 1: The images shows all the connections that led to the final capacitive touch sensor.

The Link shows the working of the touch sensor when you press it with your hand.
Evaluation: I personally believe that the touch sensor helped me cover a project from last semester.It was a perfect addition to the light wall hanging.I was not able to find any material as such to combine with the touch sensor which I wanted to work on specifically if we go into e-textiles.I believed that my ideation was in the right direction of working on a project that I was happy about.The touch sensor addition is a great addition and I truly believe that sometimes project connections just happen on the go when you are thinking.The sensor works properly without any code or mechanical problem.
I also believe that working on the sensor with the materials at home was not too costly for me.At a very minimum price a sensor is ready.Both the products combined are a great option for the coming christmas.

Trailing Pixels

This project was inspired by my disability and Wolfram’s Rule 30. The trailing pixels represent how I struggle with my disability. My struggle in communication, work, social life and overall life. It feels like a constant displacement and blur.


  • Draw a canvas with a restriction of 800 x 800
  • Fill canvas with an image
  • Pick a random pixel within the image
  • Analyze the pixel neighbours and their values of Red, Green, Blue
  • If you meet the certain restrictions, copy your neighbour
  • Copy and convert into that colour.

My process:

I started building a pixel array (p5 method) with just a few RGB colours to test the patterns it would create.


I wanted a larger colour palette, so I thought what if it could copy pixel image colours and reproduce a different pattern. I used an image of a previous experiment (which had lots of different colours) and it converted into an abstract canvas.

headline-image“The hermit crab always takes for his habitation the shell of another animal, often that of the common whelk.” (Jordan, David, Kellogg, Vernon, 175)

Hermit Grab is a game where players take the role of a tiny hermit crab on a beach. These crabs must first race, then fight over a single shell. The main idea for this game has its roots in a video by the BBC regarding how hermit crabs trade over shells, those unfortunate enough to be the same size as other crabs will find themselves in a sort of fight over a new home. This idea fostered the creation of our game, here we decided to pursue what it would be like to represent the idea of resource scarcity. This theme was inspired by how our pollution has been affecting multiple areas of the Earth, especially in the Ocean; a place where we have not only rising sea levels but also in acidity. This catastrophic change in the Ph of the water as negatively impacted marine life, making it hard for animals that rely on Calcium Carbonate (i.e Mollusks, Crabs, and various Shellfish) for their carapace to thrive and even survive. Hermit Grab places users in this position of survival as these crabs are not only fighting for a home but also their lives.

Players’ Relationship

sprite-001There are two players that they are in a competitive relationship. They compete to get the only one shell. The player with the shell at the end of the game wins.

Development Overall



Rules of the game:

  • There will be 2 players
  • Players can move the crabs by pressing the arrow keys
  • When you touch the shell, you will get the shell
  • The player who does not have the shell needs to touch the player who has the shell, in order to get the shell
  • 60s each round, the player who has the shell at the end will win the game

Wireframe Planned Game


  • We would like to add more players to the game, so the competition will be more complex and interesting.
  • Add more rounds to the game, instead of only one round. Players’ scores will be count on the main page.
  • Add more function keys to the game. For example, set key “D” as grabbing the shell, key “W” as throwing some obstacles, etc.
