Week 8- 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)

DC fan controlled by Bluetooth

I searched on Arduino project hup, I found some projects but I do not have the component.

So I search in my kit to make a project and learn new things.

I decided to make a DC fan controlled by the Bluetooth module.

Tool Chain

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

Tinker Cad to simulate the circuit before doing it with a real components.

Breadboard to make the wires less as possible as we can.

Arduino board to upload the code on it.

DC fan to make an action( open and close)

Bluetooth sensor to control move of DC fan.

Jumpers to connect the components

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?

At the first I opened Tinker to simulate the circuit, I didn't find the Bluetooth sensor so I searched about a project and I use it.

I made some edits, delete some components, so I can use it as I want.

After that I searched about the DC fan ,but I didn't find it, so I used the DC motor because it is similar to DC fan.

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?

I started to connect the components together and connect them to the Arduino board.

First I connect the Bluetooth module to the Arduino which RX of Bluetooth module connects to TX of Arduino and also TX to RX, the ground and power connections to the breadboard which I connect the ground and power of Arduino.

Second I connect the ground of The DC-fan to the ground of Arduino on the breadboard, and the power to the 13 pin on Arduino to take the sign from Bluetooth.

I started to write the code

first I declared the data with initiative, so I can use it in my code without errors.

Second, at the Setup class, I wrote the things that need to happen once. I started the serial to open the communication with the Arduino and declared the pin of DC-fan.

Third at the void. I wrote the code which will repeated all the time in the loop, I wrote if, else condition that will open when receive H from app and close if did not recieve anything.

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?

At the end of week session, some errors happened at our code and Mohammed helped us to fix them.

Sharkawy helped me at the assignment which I had a problem how to connect the fan to take the signal from the Bluetooth module.

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?

Also I had a problem with the Bluetooth module, it did not connect to the Application.

I make sure that the connections right and the code also, and I change the Bluetooth module but it didn't work too.

When I was connecting the components to the Arduino I connect the power and ground of Bluetooth on the breadboard in the wrong way, and I noticed that the Bluetooth does not blink as supposed to happen.

So I checked the connections again to make sure that everything is right, and I figure out the mistake and correct it.

Final Project

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

I do not think that I will use the Bluetooth sensor in my final project, but this week is very interesting which I learned how can I control a component remotely with the mobile phone or the PC.

WOW!

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

Title of Media

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.
