Week 6- 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)

Smart DC Fan.

My idea for this week's assignment was about a smart DC fan controlled by IR Sensor. The green LED is emitted as long as there is no signal from IR and if you put your hand near the IR sensor, the fan will run automatically and the red LED will be emitted and the green will turn off. So, there are 2 outputs:

Running the fan.
Changing the LED color.

Tool Chain

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

Soft ware:

I have used the TINKER CAD platform for simulating the electronic circuit.

Arduino IDE to upload the code for Arduino.

Electronic Components:

9V Adaptor.
Brushless fan DC 5V.
Bread Board.
Arduino UNO.
IR Sensor HW-201.
2 Light Emitting Diode (LED).
Two 220 Ω Resistor.
Motor driver L298N.
Jumper wires.
USB Cable.
Adaptor Socket.

Title of Media

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?

Simulation Process

I Used the TINKERCAD platform to simulate and view the schematic of the circuit which helped me to understand the process

TINKERCAD Simulation

Coding Process

Block Code

Block Code:

As a beginner, I don't have experience or knowledge of coding. So, I have used the TINKERCAD platform to program the circuit with this interactive blocks which helped me to do what I want.

Arduino Code:

After I have finished the block code on TINKERCAD, I copied the text code from it and dragged it into Arduino IDE as shown.

This circuit has been programmed based on the conditional" If". As if the IR sensor detects a signal, the fan will work and the red LED will light up with it, otherwise, the fan will not work and the green LED will remain light.

Note:

You have to verify the code before uploading it to Arduino to make sure that there are no mistakes in the syntax of the code otherwise the circuit won't work properly.

Arduino Code

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?

Integration Process

Building the circuit

Building the circuit:

I used the electronic components I mentioned above to build the circuit of the project.

Connecting the "L298N Module":

This step was very necessary to make the fan run because the output current of the Arduino is not enough to power the fan. So we have to use this piece and here is the method of its connection.

Final Outcome

Final Outcome:

Finally, After many tries to understand and run the circuit it worked properly.

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?

Actually, I was facing a problem when I tried to operate the circuit because the fan hadn't been started. So, I found the problem when I had opened the "community-troubleshooting" group on slack and my classmate Mohamed Ayman had faced the same problem but he overwhelmed it by using a motor driver module LM298N

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?

I got stuck when I had started to test the circuit. The fan couldn't start because I had forgotten to connect the motor driver module LM298N as the output voltage of Arduino didn't enough to operate it as shown in the video attached. So, I used google to understand how to connect it with the circuit.

The reference that I depended on

Final Project

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

It was my first time dealing with the Arduino IDE. So, I got familiar with it and it will help me during working on my final project in the point of programming.

WOW!

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

I have earned a variety of skills and knowledge in this week as follows:

Controlling several components by analog and digital inputs.
Understanding the concept of analog and digital output.
Getting familiar with Arduino IDE.

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.
