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 assignment of this week is Build and Program a smart device that perform a certain function or solve a problem using an Arduino UNO at least two input and two output by using Arduino C (Text Code).

My idea:

First, I was interested to do something like my final project which it is a laptop cooler. then I decided to make it with the final circuit by using cardboard to test my self and my ability to do my final project and also to saving time during the two weeks of the final project .

Tool Chain

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

Software:

Tinkercad

To test my circuit to make sure that it is works without any problem and simulate it

Arduino IDE

to write the code and upload to the Arduino

Machine: ..............

Materials:

Cardboard

Wax

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?

Firstly: Prepare before design

By searching for more ideas
Sketching a free hand design with pen and paper
Detect the cardboard Parts

2- Electrical Circuit

Create new circuit
Detect the components needed Arduino, PIR sensor, Motor, Breadboard, Temperature sensor, led, resistor and relay ) and i used the the power supply and the relay to give the motor of the fan an external voltage with the Arduino volt to work
Insert the components and start connect (Wiring)

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?

After wiring were finished, I start to coding and implement the design

Firstly, Start wiring the components as I did on the tinkercad

Secondly, open the Arduino IDE and then install the library of the DH11 sensor that define the type of the sensor and the reading pin, and then start to write the code and the conditions by:

define the constants

define the inputs and outputs in the setup loop
Serial print to see the sensor reading
write the conditions that if the tempurature is more than 25 c the fan will operate in the void loop
and if I put the laptop on the cooler the IR sensor will operate the led

Then upload the code to the Arduino

Thirdly, test the code with the components and the circuit

Fourthly, Start make the cardboard parts as shown in the sketch and make the body

Fifthly, Install the components in the body

At the end, Assembly the circuit with the cardboard body then test it

The final Output

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

I asked instructor Amany, when I wanted to use the temperature sensor in my final project, about her advice for which one I use , And she told me that there is big different between both and they will do the function

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

when I finish the code then upload to the Arduino and start test it does not work and the temperature read (non). I checked the wires and the sensor and I modified a lot in the code and it didn't work either

At the end I searched for the code for theDH11 sensor and found that the type of sensor is 11, and in my code is 22. after that it works.

Final Project

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

I learned how to write the code that will control the process of the final project and the connections of the Arduino

WOW!

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

The coolest thing that I have learned this week is how to write a code and I made the first code in my life and it is works

Weekly Digest [OPTIONAL]

Tell us about any other cool things that you've made this week: in the Hands-on activity, tutorial examples, exercises, or any other cool mini-project that you tried out aside from the assignment.
