Introduction

About me

Hello, my name is Payal. I am studying Industrial Arts and Design practices at Srishti Institute of Art, Design and Technology. I have developed interest in electronics since the last sensors class. I have made tiny circuits for different projects in my products and I feel I can reflect some of my electronic learning in further projects as well. Learning Arduino coding was kind of difficult for me initially hence, this class I am looking forward to get hand of the Arduino and explore more sensors.

Touch me not monster

In this particular task, we made a creature which works of Arduino Uno, servo motors and IR sensor. While making we face slight problems in the coding and connections of the IR sensor. The coding was going wrong which was difficult to figure out. The serial number reading wasn’t changing from zero. Also the coding at the point when we had to synchronize the two motors and add in values accordingly. Overall it was a good revision to the previous sessions as I realized while doing that there were many things I had forgotten about. Though a quick throwback, I kind of can now relate to the equipment and figure out a little coding as well.

Resistors in Series and Parallel

Resistors in Series

Consider two resistors R1 and R2 Voltage V Current I

The current flowing I will be opposed by two resistances. The equivalent resistance will be the sum of the individual resistance. If current flows through R1 and R2 the voltage will drop at those two points. By Ohm’s Law, V1= IR1, V2=IR2

Total Voltage V= V1+V2

V=IR1+IR2

V=I(R1+R2)

V/I=R1+R2

But=IR

IR/I=R1+R2

R=R1+R2

Resistors in Parallel

Consider resistance R1 and R2. Voltage V Current I Here the current gets divided by the two resistance connected in parallel. Therefore total current (I) = I1+I2 By Ohm’s Law,

V=IR

Therefore, I=V/R

Substituting in the equation,

I= V/R1+V/R2

I=V(1/R1+1/R2)

V/R=V(1/R1+1/R2)

1/R=1/R1+1/R2

The first half of the class was a basic introduction to the necessary terms. It was again a revision oh what we learnt in our physics class. It now can relate to the fact how these equations play a vital role in building the circuits. I remember how once we had shot the LED while we were working with the revision project as we forgot to apply a certain Ohm resistor to the circuit. I am looking forward in learning the conversions as I feel I am kind of lacking I the basics.

The second half was really fun. It was good experience to visit the place and collect samples. We collected around 8 samples from different areas. Some with clear water some with algae and some with moss and rainwater puddles. We also have taken soil samples. The place had a peculiar smell in the beginning like too many harmful gases were mixed together. Also, the place was dumped with a lot of waste. In spite of this there were a lot of birds wandering around the lake which gives a clue of there being fishes or some food they rely on. We found some water creatures as well which can gives us an idea about the clarity of the water. Looking forward to understand the organisms and what role they play and how can we relate sensors to these creatures.

Air Quality Sensor

In this particular task, I had to develop an air quality sensor. It was a good learning experience as I learnt a little more about Arduino coding. Initially the coding was going wrong as I had not entered the correct analogue pin number. I was able to understand the connections and the pins of the sensor.

Turbidity Sensor

We developed our own turbidity sensor. Building your own sensor felt like some achievement. Initially I was kind of worried how we build our own sensor. After understanding the connections it seemed easy as it was based on a LDR which we had studied before. After the connections we tested it and it worked fine. Later we placed it in the box it started misbehaving. I wasn’t able to understand what went wrong. Later after some time I realized I had done the connection wrong while reconnecting while placing in the box. We tested it with samples and it worked fine. A slightest change of pin made a huge difference to the working. It was interesting to learn making of such sensors as the huge machines are built on the base of such a small connection.

Draw whatever you want

Cyborg, Post Human

For Cyborg I drew a human which has a robotic head and a normal human body. The body functions like a human but the thinking and the working of the brain is robot. Basically can be controlled. For post human, initially I drew a weirdly looking creature but later I drew soil particles which shows the disappearance of the human race.

Futuristic Gadget

For this particular task, I was paired with Aman. We made a head gear which had an antenna which could read everyone's mind. Also, the headgear had a mic which can be used to talk of things which a person wants the other people to obey or listen.
