Week 1 - Journal

Air pollution trapper

  • We have a secret killer called air pollution, while you are happy walking in streets it may kill you. So I decided to start kill it before it kill me.

  • according to 17 sustainable development goals #Climate_action

  • as an individual in living organism community we have to reduce harmful gases which cause Climate change and harm all living organisms.


Tool Chain

  • forelectric circuit hardware

for the simulation of the electric circuit software.

Design/Preparation Process

Enclosure


It’s a box contain hole for the fan

simulation

tinkercad

tinker cad simulation

Electricity

my circuit contains

1) Voltage applied is 9V from adaptor because i used 1.8 LED and 5 V for fan

2) Two kinds of connections

Series:

Between the lamp and resistor

Between On/Off switch and all components

Parallel:

Between the lamp and Fan

Mounting

my box contains a shelf to put the breadboard on

Development/Implementation Process

for electricity

  • Ohm's law has been used to calculate specific voltage. which is 9 V

  • i use resistor to save the LED

  • i use tinker cad to try my circuit first

for the design

  • i cut holes for the adaptor and switch and lamp

  • i cut quarter for the fan

for the development of my project idea

  • vasaline covered material can attract pollution so i used it to trap pollution.

Community of Learning



  • in face to face session i worked with Mina to connect the H bridge circuit and i learnt alot from him.

  • this was my first time to connect circuit with breadboard i can't imagine it well at first but my instructor helped me to connect a series circuit when i couldn't do it .

i

WOW!

i learnt how to make a car.

and Finallyyyyyy i will make my students make cars!!!!!!!!!!


Overcoming Challenges


I was having a problem in stimulating the switch in tinkercad i forgot that we connect the switch from common and one terminal

but after searching I did it.
