WEEK VII - 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)

Inspirational picture of the design

The main objective of the assignment was to develop creating electrical circuit design with more complex code & extra functionality that provide more accuracy.

I decided to create simple color gradient measurement that shows warm to cold hue depends on positioning.

TOOL CHAIN

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

I- Electronic:

Software:

Thinkercad (to make sure the circuit if functional).

Arduino IDE (to load programming code to the arduino).

Material:

Arduino Uno.

7RGB LED.

220-ohm resistor.

Ultrasonic sensor.

Push button.

Servo motor

Breadboard & crocodile wires.

Power adaptor, Rosetta & USB cable.

Softwares & materials used

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?

I-Circuit (Thinkercad)

Step (1): I started creating the circuit by place & connect Arduino & breadboard together.

Step (2): Then I added Ultrasonic sensor to the bread board & linked it to the Arduino.

Step (3): Then, I added RGB LED with separate resistors for each pin & connected it to the Arduino.

Step (4): After that, I added servo motor & connect the Arduino.

Step (3): After that I added push button that would control servo motor & connected it to the Arduino.

II-Code

Step (1): I started by calling servo motor function.

Step (2): Then, I sat colors mode depends on ultrasonic distance readings (ex: from 60 to 70 it creates blue light).

Step (3): I created mapped angle to change range of color from 0:100 to be 0:180 which is servo motor range.

Step (4): I created functions for each color by changing RGB values to create different colors.

III-Simulation (Tinkercad)

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-Circuit (Building Components)

It was easy step to build the circuit as it was designed.

II-Circuit (Testing Components)

Testing ultrasonic reading, it was perfect.

Testing servo motor motion with different reads.

III-Circuit (Full Circuit)

It's time for testing colors effect on both motion & light.

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)

The problem that bugged me the most was the RGB LED calibration, as I wanted to provide a wide range of colors from warm to cool but I wanted it also to show the exact needed color not any unexpected hues, that's why I had to test many hues specially for secondary colors to achieve colors I like to have for testing out of different values & combination.

Final Project

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

I would say that it was the huge coding week as, it was full of practice on coding the Arduino on different techniques, that made me more & more familiar with writing & understanding the code to be able to create what I needs in my project.

WOW!

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

Well, I guess the most interesting thing that I learned this week was how to create more than mood for one device and how switch from manual to automatic mode Also, the concept of serial monitor that helped a lot to understood how it works.
