Week 7 - Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)

the ides are inspired by the fan but I need to make it smart I will use an infrared sensor to feel objects and Temperature Sensor when temp > 30 then the fan will open and the red led too.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

USED SOFTWARES

I use Arduino software to typing code .

MATERIALS

cardboard

Infrared Sensor

L298N H-bridge Module

Mini Breadboard

LED

Arduino

Jumper Wires

Scissors

Microbot USB Cabl

DC motor

Glue Gun

DS1820 Temperature Sensor

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

https://www.tinkercad.com/things/cwTaGvjxqqu-frantic-snicket/editel?tenant=circuits

here is the circuit on tinkercad.

Frist step start with cutting the cardboard regard to fan design

then I building the circuit I stared by led I was connect it with board and resistor then connecting with Arduino

then I connect the sensor with Arduino

I did a search to find out the data sheet of the motor control and how to connect it with the motor and the correct way of wiring , and to know the output pins and input pins

then I was connect Dc motor with H bridge and like to Arduino

and then I attach Temperature Sensor to the A0 pin .

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

here I was writing the code to order Arduino when the infrared sensor sensed an object or Temperature Sensor temperature <= 28 then the red led opened and the fan worked too.

then I tested it after I attached it with the cardboard model

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

He explain to me what h bridge included we can use for working two motors in my case I used it for one motor so I will wire it to the motor like in the above picture and then I attached +5v and GND with Arduino pins GND and +5v and wiring input 2 to pin 11 at Arduino

when I make a circuit Frist time it wasn't working because I put a relay instead of an H bridge then I asked Abdulrahman oraby coordinator and then he help me alat and explain to me how can I use H bridge thanks abdalrahman

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

Here my smart fan device was working finally.

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
