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)

This week's assignment is to Communicate wirelessly with a Smart Circuit via a Graphical User Interface (GUI) on your phone or PC.

Smart Door

A smart door is a mobile-controllable system that improves the quality of life.

Tool Chain

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

Software

Arduino IDE
It is an open-source Software (IDE) that makes it easy to write code and upload it to the Arduino board.

Arduino Bluetooth Controller App

This is an Android app that allows us to control any other device using Bluetooth.

Tinker CAD
Tinkercad is a free software for 3D design, electronics, and coding,
I used it to design and simulate my circuit.

Components

Arduino Uno

Connecting Wires

Breadboard

Bluetooth

16×2 LCD screen

Servo Motor
(Action Component)

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?

Circuit Design On TinkerCAD

First, I used an Arduino Uno board to control my circuit.
I used a Servo motor to open and close the door.
I used an LCD screen to display the status of whether the door is open or closed.
I used the BT module hc-05 to control the device above through smartphone.

The servo is attached to pin 7 on the Arduino board.
The LCD screen is attached to pins A4:A5.
The black wires are attached to the ground.
The red wires are attached to the power source.

Code on Arduino IDE

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?

Prototyping On Breadboard

Final Result

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 first time the code was not uploaded because the Tx and Rx of the Bluetooth module were attached to the Arduino pins.

By reviewing the instructor's advice, I found that we should detach the Tx and Rx of the Bluetooth module.

Final Project

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

WOW!

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

Weekly Digest

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.
