Week # 8- Journal

Ideation

Tell us about your assignment's idea for this week. Why do you care about this idea? What were you inspired by?

Doing a simple idea of controlling LED and a fan through arduino by using an application on your phone to resemble a smart home.

A smart home allows homeowners to control appliances, thermostats, lights, and other devices remotely using a smartphone or tablet through an internet connection. Smart homes can be set up through wireless or hardwired systems. Smart home technology provides homeowners with convenience and cost savings.

Tool Chain

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

The electronic components:

Breadboard.
Jumpers.
LED.
Resistors.
Arduino.
Bluetooth module.
Fan.

The software :

Tinkercad.
Arduino.
Bluetooth terminal application - android system on google play.

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?

Making communication between the laptop or mobile and arduino using application. "Android".
TinkerCad has no bluetooth or wifi module so the circuit eas prepared on the breadboard right away so I found wiring diagrams on fritzing.

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?

Writing the code on arduino

Uploading the code

Make sure the bluetooth module works

The fan is connected to pin 13 and the led is connected to pin 12 , the bluetooth module is connected to pin 0 and 1 "TX and RX" where they are connected inversely.

through the mobile application the bluetooth module receives the data and orders the fan and LED to work as in a smart home.

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)

1- Having ios on my phone so it was difficult to find a way to work with android system.
solution : Using the application on one of my peers mobile phone or at least control the model using serial monitor.

2- Writing the code might be a little difficult.
solution : checking the code on tinkercad or fritzing to make sure it works through the simulation first.

3- A trouble in uploading the code.
solution : Remove the jumpers from the TX and RX pins from the Arduino during the uploading process.

Final Project

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

Understanding the mechanism of Bluetooth module and how it will affect the movement of motors and accordingly the model parts in my graduation project as part of my nice to have properties in the project to control it manually using the phone rather being controlled automatic by outer effects through sensors "LDR module".

WOW!

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

Making the Robot arm with Mariam and Ahmed.
