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 .

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.
