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)

The Assignment for this week is to Communicate wirelessly with a Smart Circuit via a Graphical User Interface (GUI) on phone or PC.

My idea here is to build a simple smart home that can control Sound and light with my mobile wireless.

Tool Chain

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

Hardware

Arduino UNO to control the system.

RGB led for light.

Buzzer to create sound.

Jumpers for wiring.

Bluetooth Module to communicate with mobile phone.

Software

Tinker Cad to simulate the design before wiring it.

Arduino IDE to write and test and burn the code.

Arduino Bluetooth controller android app to send commands.

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?

First set pins mode in setup function to be output for motor and buzzer.
Give names to pins to be more readable.
Start the loop function with a while loop that waits until the user sends commands.
If the user sends '1' that means he wants to switch the buzzer.
If the user sends '2' that means he wants to switch the light.

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?

Connect the buzzer to the ground and pin 2 in Arduino.
Connect led to ground and pin 3 in Arduino.
Connect Rx in Bluetooth module to Tx in Arduino.
Connect Tx in Bluetooth module to Rx in Arduino.
Power the Arduino using a 5v Adapter.
Use Mobile App to send 1 or 2 to the Bluetooth module.

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)

I was very sure of the connections, but the buzzer did not work well, so I used the Avometer to check the jumper and it was the problem, then I replaced it with another one and it worked well.

Final Project

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

I learned how to use The Bluetooth module and its connection and wiring technic.

Also, I learned how to use a mobile application to send commands wireless.

WOW!

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

The challenge of fishing was very interesting and not only learned how to make this thing, but we also learned patience.
